Reworked whole Version Checker with an extensible interface to add any other service later on easier.
The version checker now has its own config file, to collect the different options and extract them from the main config file.
In that you can specify how fine the versions should be checked.
Added temporary(!) API dependencies, will resolved via Maven later on
Added mcmod.info
Added pack.mcmeta template
Added hacked BC jar to use facades indev
Split build logic into several pieces
Update gitignore
Modify build.gradle to match changes
