Support for PC platform (#12)

* improvements for cross-platform compiling * moved tactility-core to libs/ * splitup improvements * remove git/gitmodules from freertos * better platformbetter platform checks * added build scripts * delete mbedtls * re-add mbedtls * fixes and improvements * added pc build * simplify build scripts * revert build scrpit * updated builds * fix for pc * fix for pc * fix for build
