Fix compile (#199)

* Fixes made so far

* Fixes up until linking

* Moved GetInterpreter() to a single function under the Engine.h

* Updated shader files included with assets, added exception for Linux for including SDL2_net

* Removed osSetTime stub(for now)

* Adjustments to get it to compile + run

* Decoupled GetInterpreter() from the GameEngine Class, corrected a invalid include in SpaghettiGui.cpp
