- Create `Include/` folder for all main projects - Fix some issues here and there (found while moving things) - All includes are now in `Tactility/` subfolder and must be included with that prefix. This fixes issues with clashing POSIX headers (e.g. `<semaphore.h>` versus Tactility's `Semaphore.h`)
