Title: Fix division of MIDI files in format "fps and ticks per frame"

There are two ways to specify the time division of a MIDI file:
beats per second + tempo event OR frames per second and ticks per frame
(see here: http://www.recordingblogs.com/sa/tabid/88/Default.aspx?topic=Time+division+(of+a+MIDI+file)).

The second case was processed incorrectly in MidiFile class and in MIDI import, so this is a fix for it.
And here is a test MIDI file:

Now it is imported correctly.
