add_segment convenience method
line wraps
envelope-map effect
remove DMX keep-alive
not bombing on start
sort out intensity transfer - seems to basically work

expecting lots of bugs lurking
only set device intensity if device based
put higher level color logic on logical device
add an audio player multi-play class
disable print
make sure to only add device to network once
restore framerate status print
disable mode feature

now that logical and physical devices are separate
blend modes have to be rethought
