add "remove_components" feature

If one do not want to use some components in the RTT_ROOT, it can pass a remove_components=['the_component'] parameter to PrepareBuilding. Sample code is:

RTT_RTGUI = os.getenv('RTT_RTGUI')
# if GUI dir is set to other place, don't use the one in RTT_ROOT
if RTT_RTGUI:
    # prepare building environment
    objs = PrepareBuilding(env, RTT_ROOT, has_libcpu=False, remove_components=['rtgui'])
    objs += SConscript(os.path.join(RTT_RTGUI, 'SConscript'))
else:
    objs = PrepareBuilding(env, RTT_ROOT, has_libcpu=False)

You can safely omit the parameter if you do not want to remove any components.
