show the name of the model installed when there is only one

InstalledLanguagesViewController and LanguageSpecificViewController changed ids

LexicalModelState is not needed, KeyboardState has all the values we  need, note where we need to put a dialog when there are no lexical models for  this language

the branch this depended on was merged to master and deleted

[ios] UI LM Management

[ios] Add keyboard from Language Settings

[ios] test target and swift reachability

Merge pull request #1871 from keymanapp/developer-lexical-model-compiler-include-fix-1861-regression

[Developer] Include index.ts in tsconfig.json for Lexical Model compiler

[web] [iOS] [Android] Adjust position of subkeys and key previews

[ios] Update installing a multilingual keyboard from local kmp package

Language Settings can now add a new keyboard via LanguageSpecificViewController, a subclass of LanguageViewController
LanguageViewController made more easily subclassable so languages variable doesn't have to be exposed

[Developer] Remove Object.values() in favour of Object.keys().

begins work on keeping better track of languages and related data
