Version 0.3 - Optimisation

Version 0.3 : 

This release significantly improves rendering performance. Larger screen resolutions no longer have such a major impact on game performance, and in some cases rendering is now up to 30 times faster

Optimizations :
- Considerably diminish the time spent to draw a frame

Misc :
- Change color of stabilization on the instable dreams

Version 0.3.1 :

Bugfixes :
- Building cost on tier 2+ now correctly deducted
- Instable dreams not manually destructible anymore

Misc : 
- Movespeed tied to time and not frame (speed decoupled from FPS)
