First step toward adding plugins support
Plugins working, all detectors have been moved from core to plugins
Simplified base class Actuator
Some cleanup
Merge branch 'plugins' into develop

Conflicts:
	Makefile.am
	configure.ac
	src/Makefile.am
	src/blobserver.cpp
Small updates to Makefile.am and configure.ac
Re-added Actuator_ArmPcl
