refactoring of repository:
* added stuff to catkinise this repository (now strands_morse is the package, everythnig else is contained in it)
* the policy is that different environments can go into different subdirs (simulator.sh takes care of setting everything up)
* changed simulator.sh to set PYTHONPATH etc and removed this from the specific builder scripts
* move all non-simulation code (strands_executive) into subfolder TO-BE-MOVED for now
* created new environment tum_kitchen
* put everything that is common into strands_sim (robots, scripts, etc), make sure other environments can find what is in strands_sim
moved simulation urdf file into strands_sim/robots
added removal of file
moved 2dnav out of sim repository
added missing resource path
