Clean up the code.

[betterclever]

The code is written in very unprofessional manner in various parts. Silly on my part. I would really appreciate properly cleaned up code including:

• Uniform Variable and Method Naming Styles . (Use camelCase)
• Removed unused imports (if any) .
• Removed log statements.
• Proper Indentation everywhere (using 4 spaces).

Note: Do the above only in core module. Changes not required currently in Android, BaseGameUtils and Desktop module.
