Ported to Qt5
Millisecond accuracy for musical timers

Set the QTimer's type to Qt::PreciseTimer.
Error checking on midi send
Send defaults if no values for fx
Binding channel params crash fixed
Don't send channel controller values by default.

This causes a bug in the initialization resulting in the fp-4 being
reset to default values at startup. This is probably caused by sending
too much midi data directly to the hardware.
Update .gitignore to forget .user files
Fixed fx param labels at detriment of unit correctness
Fixed bogus Foobar copyright
restore fx -> reverb send
