Bug 12535 - PROG/CCSR Deprecation: Make opac translation theme independent

This patch makes opac translation files theme independent
A side effect is that current prog translation file is
renamed.

But the renaming is not added, that gives a patch of ~60M!

Current list of languages are now obtained from pref files.

To test:
1) Apply the patch

2) For your preferred language, rename opac prog file
from 'xx-YY-i-opac-t-prog-v-3006000.po' to 'xx-YY-opac-prog.po'

3) Update that language, there must be no errors
cd misc/translation
./translate update xx-YY [-v]
Check updated po files

4) Install any language, there must be no errors
./translate install xx-YY
Check prog theme for that language

5) Create translation files. Remove a language or create new lang files
./translate create zz-WW
ls -l po/zz-WW*po
check there are 3 files (and *~) for opac

6) Check updated pod for LangInstaler.pm and translate script

When PROG/CCSR themes are removed, I'll add a Bug to remove
corresponding files.

Perhaps RM could add a followup to rename all files,
cd misc/translator/po
for old in $(ls *opac-t*); do
    new=$(echo $old | sed 's/-i-opac-t-prog-v-3006000/-opac-prog/');
    git mv $old $new;
done

Bug 12494 - Remove yuipath system preference

With the OPAC prog template going away, the only remaining use of the
yuipath preference is on the basketgroups template. The yuipath
preference should be removed and the local path hard-coded.

This patch:
  - removes yuipath handling from C4/Templates.pm
  - removes the preference from sysprefs.sql
  - deletes the preference via updatedatabase.pl
  - removes the preference from the staff client preferences file
  - removes unused references to the YUI assets from the help file
    header include
  - adds the local YUI asset path to acqui/basketgroup.tt

To test, apply the patch and run the database update. View some online
help pages and confirm that they function correctly. View the
basketgroups page (Acquisition -> Vendor -> Basket groups), edit a
basket group, and confirm that basket drag and drop operations work
correctly.
