0.5 Mega commit
This "mega" -commit introduces some major/breaking changes:
The highlights are:
- Switch from the ufsm-core runtime to statically compute everyting in
the code generator - The generated code is now stand alone and does not require the
obsoleted ufsm-core library - Switch to cmake as build system
- The ufsm-model library has moved in with the ufsm-compose tree since
it's no longer shared between the generator and the compose tool
