Prepare for splitting out WaveNext by using StackedWidgets...
Initial whack at separating WaveNext out into it's own host within the
host protocol I'm developing.  It mostly works (except for all of the
shit that's broken).
Use the main transport's time label for WaveNext
Fixed wave editor plugins (I think)
Centralize PLUGIN_UI_DICT, since the plugin pool itself is centralized
Various fixes and improvements to how plugins are set
Fix WaveNext's peak meter
Fix the "open in wave editor" functionality
Add wavenext.py files to RPM SPEC
Fix the power buttons on the wave editor effects not turning them off...
Fix the normalize dialog in the wave editor
