Bug 7167 follow-up

Major changes:
* creating database tables for update on the fly, the  1st time the update script is called
* version is checked on mainpage.pl (and here only). If syspref Version differ from kohaversion.pl, the old updatedatabase is launched. If there are updates missing from new mechanism, the updatedatabase page is reached
* kohaversion check on each page is now useless in Auth.pm, removed dead code
* Updated installer: at the end of the process, retrieve all updates and automatically mark them "OK", as they're included in installer

Minor changes:
* adding copyright
* adding poddoc
* updating a warning, for better clarity
* switching from $$var to $var->
* small TT glitch fixed in updatedatabase.tt
* about.pl now returns the Version systempreference PLUS all the patches that have been applied

Bug 7167 follow-up perlcritic & numbers display & partial apply depending on DEBUG

* add use strict to updatedatabase, that is now perlcritic compliant
* partial apply of DB revs is now managed by DEBUG env variable = if DEBUG=0, the user can just apply every DBrev. If DEBUG=1, we're in a dev env, the user know has the option to apply DBrevs one by one
Display:
* in updatedatabase, small spelling changes
* in about.pl, remove 0 just after . (3.06.01 is displayed as 3.6.1)
* improve the display of applied numbers on about.pl
 - before this patch, if you have N, N+1, N+2, N+3 and N+10 DB rev applied, about was displaying : , N+1 / N+2 / N+3 / N+10
 - after this patch you have N......N+3 / N+10
* add ORDER BY into list_versions_already_knows to have number retrieved in the same order whatever the order they are applied

Bug 7167: Remove check_coherency

As suggested by Katrin, we've removed the call to check_coherency. It intended to provide readable comments when some SQL was wrong. Removing this sub result in the SQL error being displayed. That's OK because the sysadmin or the developer can google the error, understand it, then fix it.

Bug 7167: Changing in .sql parsing

We first split on delimiter and then extract comments. You can now put
\n for delimiter comments.
ex:

DELIMITER ;
-- this is a comment
SELECT * FROM  my_table;
-- another comment

Before this patch, we had to write:
DELIMITER ;
-- this is a comment;
SELECT * FROM  my_table;
-- another comment;

Bug 7167: Add .pl and .sql examples

Those files are in version directory, so will never be executed by the updater
If you want to provide an update, do it in a 3.09/ directory (if your update is expected for 3.10 version)

Note that the updater use a md5sum checker. So, if the same update is in 2 different places, it will be detected. That will be handy for changes made on both stable and master: a library running stable will get the update when updating. When upgrading to the next major release, Koha will detect the patch has already been applied, and no error will be thrown. With the previous mechanism, a DBRev ported to stable was re-executed when upgrading to master, resulting in a nasty (but usually harmless) error message

Bug 7167: Improve display + factorize get_queries

Despite it's size, this patch is dealing with display questions only:
 * The text "comments" and "queries" was hardcoded in ajax-updatedb-getinfo.pl script. It has been replaced by a JSON call, returning 2 separate values, "comments:" and "queries:" is now in the template, making it translatable
 * Some minor tweak in the display (like putting things in bold, displaying OK in green, warnings in yellow and KO in red)
 * Reordering the column headers for more readability:
    * Status column is merged with availability, column is after status
    * Status/availability terms more clear: "Not applied" instead of "unknown", "Applied and OK", "Applied and failed", "Applied and forced" are the 3 other statuses
    * Removed one click to display comments on DBREv not yet applied: before the patch, one had to click "Show details", then "Get comments", now, "Get comments" is enough

Now, a non-numeric DBRev will be applied if you provide the --all parameter, without throwing the error

Bug 7167 reindentation & removing dead code

* The if (! defined $ENV{PERL5LIB}... block was wrongly intented
* The 3 lines running update.pl are useless: the update (new mechanism) is run from admin/updatedatabase.pl script. This part of install.pl is run only when you have "old style" DB revisions.

Summary:
 * old mechanism = it's run as previously, by reaching the installer/install.pl?step=3 page, that applies all revisions
 * new mechanism = when you log-in or reach mainpage.pl, you reach admin/updatedatabase.pl, where you can see what will be run, and run it

Tiny side effect = the check for old mechanism is now done *after* authentification (thus it's not done on each page call). It means that the user will have to enter login/password twice :
 * first to log-in to Koha
 * second to run installer/updatedatabase.pl?step=3
As the old mechanism is deprecated, we can expect this will happend only a few time in the history of a setup, it's not a big deal.
