Investigate better storage location for CMake and init.rb stuff

Suggestion

It should either go to package set or individual repository included via default build layout.

Rationale

All ESROCOS features should also be available form user-customized buildconfs

Over the last days I have experimented a bit with that topic. In #18 some files are already moved out of the buildconf into a new package "tools/config".

Candidates to move out of the buildconf would be:

• The init.rb parts exporting / setting environment variables
• cmake_modules (should be installed)
• templates (should be installed)
• cmake_macros (should be installed)

However, I stumbled over multiple problems:

• many other packages would need a explicit dependency to ensure tools/config is always installed first
• Although setting the CMAKE_MODULES_PATH in the init.rb the modules would not be found by the packages
• the environment variables seemed only to be reliably when set in the autoproj folder (i.e. the buildconf)

So essentially I was only able to move out the templates and cmake macros functionally but perhaps this is not a problem of principle but only of my autoproj-fu. Next week I might look more into this.

what about moving these things to the package set?

Update:

• worked out the problem with the cmake modules (was set concurrently at two different points, my bad)
• Many of the variables could also just be set in the cmake file instead of the init.rb (and thus reliably outside of the buildconf) but I am not quite sure if that would be good practice
