Quick Mix renamed to "Mix and Render"
Keeps track name the same if you just render
More informative history/undo messages
Now correctly initializes the rate and end/length radio control.
The end/length radio control is now saved as a preference.
Modifying the selection bar now more or less works properly;
it doesn't try to second-guess you while you're typing.
Not perfect, but definitely usable.
Double-clicking selects the current WaveClip if you're over one,
otherwise the whole track.
You can now move multiple WaveClips at once: if you click on a
selected part of a clip, then every clip which intersects the
selection moves simultaneously. Only horizontal moving is allowed.
The selection moves along with the clips. Alternatively, if you click
outside the selection, only the clip under the cursor (and its linked
clip, if stereo) moves.
Currently this doesn't work properly with multiple clips in a row
horizontally (it works great for sliding clips from multiple tracks
all at once); I will fix this soon.
