Bug 13632: Use an include file to display permissions

This patch set moves the permissions' descriptions to the po files
instead of having them in the DB.

Test plan:
0/ Apply all patches
1/ Create a new installation
2/ Confirm the userflags and permissions tables are correctly populated
3/ Update the po file for a translated language
4/ Confirm you are able to translate the permissions descriptions
5/ Install the template files for this language
6/ Switch the interface to use this language and confirm the string are
correctly translated.

QA Note: At this point we could remove the userflags.flagdesc and
permissions.description DB fields, but I would prefer to keep them:
developers will know what the permission do without the need to go and
see the include file (we have it in the sql files and so, in the DB).
