Moved tests to separate binary (mbpfan-tests)

Removed instructions for using -t flag
Moved check_requirements function from main to mbpfan
Moved daemonize and verbose globals from main to daemon
Moved strings for program information from main to global.h
Moved strings for coretemp and applesmc paths from main to mbpfan.c
Updated Makefile
Turned on verboseness for testing
