Update to maintenance release version 2.2.1
Upstream changes and fixes:
*Waveform colorways:
You can optionally change the colorway of the waveforms
displayed in your project. The setting is per track and not per
project so you can have multiple colorways in the same project.
*"Save Other" reverts to "Export" in the File menu:
When we made the menu changes for 2.2.0 we introduced an entry
into the File menu called "Save Other" which led to a sub-menu
for exporting various audio formats.
Many users were confused by this change and found it hard to
find where they could export.
*Bug #1770 - Crash applying certain chain files
*Bug #1783 - Preview fails when selection extends before zero
*Bug #1787 - Auto-scroll stopped working in 2.2.0
*Bug #1765 - Using File > Open to import audio gives wrong zoom
level and no scroll bar slider.
