Add Russian keyboard

[andrewtavis]

Adding a Russian keyboard to Scribe is a major priority. Russian has all the characteristics of a language that Scribe could really help with. Beyond this, there is as of now a good amount of data on Wikidata, as can be seen in the queries.

A baseline keyboard could be made for nouns at time of writing, and once more verbs are available this feature could also be added. If the verb support isn't there for an initial release, then that feature could be disabled and message could be displayed to the user in the command bar when a user tries to use it.

What's needed:

• Russian language keyboard values added to InterfaceVariables.swift
• Fine tuning the WDQS queries found in Scribe-iOS/Data/Russian
• Writing formatting Python scripts and adding them to Scribe-iOS/Data/Russian
• Add Russian keyboard specific logic to KeyboardViewController.swift
• Setting up alternate key functions if there are keys that have them that aren't already implemented
• Adding a Russian directory to Scribe-iOS/Keyboards/LanguageKeyboards with a RussianKeyboardViewController.swift file
• Adding all the formatted JSON data to a Data directory in the new directory and updating the data table in the readme
• Add Russian keyboard specific logic to CommandVariables.swift

A creation of an English keyboard is necessary for English-Russian translation as Cyrillic letters won't be able to be used to Type English words.
