Tom Morris 03c860d961
Update jquery.i18n to 1.07 and fix non-English plural support (#2717)
* Update jquery.i18n to 1.07 and add missing rule parser

Fixes #2700
Adds missing CLDRPluralRuleParser.js so that plurals are supported.
Updates all files to jquery.i18n 1.07
Includes a bunch of specialty language support,
but only Finnish and Russian are loaded as examples.

* Add some missing translations, including plurals

Fix some cases of Javascript string concatenation and
plural conditionalization to demonstrate that plurals work
in both English and French now.

NOTE: Corresponding updates need to be made to all the other
language files since some keys were renamed or eliminated.
