Build local library and link to nodes instead of overloading executables
Added gtest

Added some simple gtests to kvh_driver. However, it seems like there is
some kind of bug in how gtest is running currently, as if you attempt to
envoke a test on a test fixture the process fails even though it says
the tests run and pass (it says they don't generate any results).
Regular tests work fine.
Refactored CMakeLists.txt to match proper ROS style
Merge branch 'master' into development-config-file

Conflicts:
	kvh_driver/CMakeLists.txt
Moved where configuration.cpp was being built into a library to reflect the new CMakeLists structure of the package
