Catkinization of cram-core

2nd try:
- 3rd party libs went (with history) to new repo cram_3rdparty_pkgs and got catkinized
- cram-core packages got catkinized
- removed 3rdparty libs from cram-core (the repo never contained the binaries)
- everything compiles BUT cram_test_utilities which has a some catkin-unrelated dependency problems

Please, someone acknowledge this.
