Bug 28267: Add warnings for database row formats

This patch adds a warning on about.pl regarding database row formats
other than "DYNAMIC". It points to the Koha community wiki for more
information on how to resolve the problem.

This patch also stops the installer if there are any database tables
with a row format other than "DYNAMIC". It points to the Koha community
wiki for more information on how to resolve the problem.

Test plan:
0a. Apply the patch
0b. koha-plack --restart kohadev
1a. koha-mysql kohadev
1b. ALTER TABLE tags ROW_FORMAT=COMPACT;
2. Go to http://localhost:8081/cgi-bin/koha/about.pl
3. Note that there is a warning about database row formats
4a. koha-mysql kohadev
4b. ALTER TABLE tags ROW_FORMAT=DYNAMIC;
5. Go to http://localhost:8081/cgi-bin/koha/about.pl
6. Note that there is no warning about database row formats

7a. Manually change the version in Koha.pm to a higher version
7b. koha-plack --restart kohadev
8a. koha-mysql kohadev
8b. ALTER TABLE tags ROW_FORMAT=COMPACT;
9. Go to http://localhost:8081/
10. Log into the web installer and click through until you reach
a warning telling you that you have database row formats other
than 'DYNAMIC'
11. Note that you can't progress with the installer until
this problem is resolved
12a. koha-mysql kohadev
12b. ALTER TABLE tags ROW_FORMAT=DYNAMIC;
13. Refresh the page or redo the web installer process
14. Note that you're no longer blocked from running the installer
due to database row format
15. Undo your change to Koha.pm
16. Profit

Note: Due to bug 32665 you'll see an unrelated warning on
step 3
