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.

* load('path/to/de-messages.json', 'de' );
* </code>
*
* To load a localization file from a directory:
* <code>
* load('path/to/i18n/directory', 'de' );
* </code>
* The above method has the advantage of fallback resolution.
* ie, it will automatically load the fallback locales for de.
* For most usecases, this is the recommended method.
* It is optional to have trailing slash at end.
*
* A data object containing message key- message translation mappings
* can also be passed. Example:
* <code>
* load( { 'hello' : 'Hello' }, optionalLocale );
* </code>
*
* A source map containing key-value pair of languagename and locations
* can also be passed. Example:
* <code>
* load( {
* bn: 'i18n/bn.json',
* he: 'i18n/he.json',
* en: 'i18n/en.json'

*
* If the data argument is null/undefined/false,
* all cached messages for the i18n instance will get reset.
