[Heavily WIP] SQRat

[tobbi]

This is, as the title says, heavily work in progress. Currently, the following works:

Calling functions of objects that have them exposed (currently: AmbientSound and Player).

For every object there is, we create a class type sqratclass_ + and an instance type: sqratinstance_ + . I know this is totally stupid, since we should create just one class type and then instances of it when the objects are created actually, but who cares. I'll fix it later, probably.

So, for example for the menu level, you can do:
sqratinstance_Tux.deactivate();

• Get sqratthread to work with internal scheduler
• Don't pass VM to each function (use Sqrat::DefaultVM() instead)
• Expose color constants to squirrel

The Travis build fails because of warnings in SQRat code, not ours. phew

Threading is bound to give us some problems. If anyone could implement the threading scripting functions, feel free. I'm struggling with them.
