Added ability for CMake to build a module from a subdirectory of src/modules.
Added calculate_libraries() CMake macro to condense library checking in CMakeLists.txt in src/modules. Fixed slight problem with strip_string() macro call in root CMakeLists.txt. git-svn-id: http://anope.svn.sourceforge.net/svnroot/anope/trunk@2302 5417fbe8-f217-4b02-8779-1006273d7864
