Add support for Minecraft Settings

- Add Minecraft vanilla settings from Settings screen
 - These settings are sent to server when joining
 - Allows to customize skin layers shown to other players
 - Most other settings are ignored by servers
 - Update language file from 1.9 to 1.10 version
 - Minor aesthetic changes in INI file comments

Suggestion by TNT-UP in issue #161 and Splodger1 in MC Forum.
