Program uses socket to communicate

small changes:
~ motorController.cpp uses galilcontroller instead of galil.h.
~ motorcontroller.h now only requires wmraTypes.h to run.

Large change (not really):
galilcontroller class is from the other wmra-lib repo.
~ Fixes some initialization issues
~ Uses separate settings_controller.conf file for ip
~ (future) motorcontroller should use this setting file as well.
