Bug 14030: Add Georgian language and fix Kannada language code

This patch adds Georgian language and a fix wrong language code

Language added: Georgian - ka - geo
I selected 'geo' for ISO639-2 instead of 'kat' because it's the
same code form http://www.loc.gov/marc/languages/language_code.html

Also a fix is needed to Kannada ISO639-1 code, from 'ka' to 'kn'

To test:
1) Apply the patch
2) Run updatedatabase.pl (once)
3) Check language, e.g. go to staff > search > More options > Limits
and search for Georgian on language list

I only added language code 'ka', not script 'Geor' nor country 'GE',
the plan is to name translation files 'ka-*', but can ammend the patch
if needed.
