using accessmodifiers in Tfmx now and removed/disabled functions that now dont work anymore (the commandline utility cant be compiled anymore as result of this)

added arraysize of external signals and check it before accesses
moved 2 debug-functions into Tfmx.cpp, removed depencies to files in the tfmx folder
moved common code for fade-effects in a seperate method
