[Cin] Use MAXCHANNELS define in mwindow.C

[Pierre autourduglobe]

I don't think we should arbitrarily limit Cinélerra-GG's ability to use 
and display track/ch sound.

Cin-GG presents itself as an NLE for pro-users or professional users. If 
a new model of sound environment (more channels) is introduced, it is 
certain that daring users will want to experiment with it and Cin-GG 
should allow it.

To the extent that it is possible to keep track/ch management and 
display easy, I don't think we should limit them simply to what is 
currently the most common...
