Tabs
Added state skeleton

* Added abstractState member to system
* Forward update, draw & input to current state
Added GameState

GameState skeleton. Gonna try some sort of state transition thing.
Would do this on another branch but loverboy is busy and I don't know
how to do branches in git. F me, right?
Added simple state transitioning flow

* Changed all event/draw calls to use RenderWindow, as intended (my
bad).
* Press space to start a transition to a new state.
* Still needs some discussion and work, so I added some new TODOs.
Discuss best practices when working with TODOs.
* Fade out uses sprite and texture stored in System. Works, but feels
ugly. Discuss.
* State transition does not actually transition to a new state. As
intended! :)
Added ContentPath to windows

* Fixed some tabs as well
Tab/space fix

For some reason this was not included in my last commit. Tabified.
