Removed the crane example…

Since it is the same as the getting started one...
Removed the test file for the getting_started

… close loop example in CGT.

I have added MATLAB and Simulink tests plus
the dummy file actually works with this one ;).
Updated and simplified code generation of examples
… in CGT

- Added macro for generation and compilation of
  exported code, see cmake/UseACADO.cmake
- Fixed crane mhe and penudulum dae examples
- Adopted the build system a bit.
