This is a follow-up to Ib6a0afa5c3736f8b9b2e121cd752c53ee50fad75 The PHP logic for grammatical cases in Russian was growing. It was too long and not reusable is JavaScript. This patch moves all the logic to a JSON file, indexed by the grammatical case name and then by regular expressions that match the different word classes, with the values being the replacements that should be compatible with common regular expression replacement functions in modern programming languages. This patch doesn't introduce any functional changes and doesn't change any tests. The next steps, not necessarily in this order, are: * Make it work also with JavaScript. * Make JSON grammar data files loadable with ResourceLoader. * Convert most or all grammar rules for all the languages to JSON. * Make the data processing loop generic for all languages. * Convert it also in jquery.i18n (Milkshake). * Convert the test cases data from code to generic data. * Move the JSON data to a separate reusable repository.
