tobid7 d815bb5674 # Rewrite Stage 1 
- Switch to CMake build system
- delete everything for a new structure
- Add SmartCtor class and saperate New func
- New Faster and Open Lithium Command API
- Rewritten Text Renderer to ghet rid of all that janky code
- New TimeTrace System and use of NanoTime using GetTimeNano
- Overall going to a more Object oriented way
- Updated vec api to support vec2 input on vec3
## Todo
- Support vec2 and vec3 in vec4 as inputs
- Continue UI7
- Fix SystemFont on 3ds freezing the system
- Fix TTF Font UV Mapping
## Warning
Creating Apps for the 3ds is not possible yet as the 3ds is Freezing and this is only stage 1 of ?   Emulator works perfect
