ones.
Added a cmd.getVersion() to get the version of mrv2 from Python.
Made playback play with audio when changing frame rate (slower or faster).

Color channels (layers) are now kept with the file so that switching between
media will not revert to the rgba channel if there isn't an equivalent one.

clip to the playlist.
Adding a clip to an EDL playlist will now positiong the current time at the
frame of the new clip, instead of resetting it to 0.
Session files also save and load the timeline viewport options (ie. Edit mode,
size of thumbnails, transitions and markers).
Thumbnail above the timeline no longer appears when there's no clip loaded
after it was shown once.
Fixed pixel zooming and panning on timeline viewport on network connections

Playlist and Editing
This is the first version that supports some basic editing and improves upon
the playlist panel by making it interactive.

The Playlist panel's functionality has been simplified. It is there only to
create an empty track or start a new EDL with one clip from the Files Panel.
The in and out points are respected when the clip is added.
Added an Edit/Frame/Cut, Edit/Frame/Copy, Edit/Frame/Paste and
Edit/Frame/Insert to cut, copy, paste and insert one frame (video and audio)
of any media. Currently, it does not support transitions, that are removed.
As soon as one of these commands is used, a new EDL is created.
Added an Edit/Slice to cut a clip in half at the current time location.
Added an Edit/Remove to remove the clips that intersect the current time
location.

Window as well as to the Playlist panel to add clips and create an EDL.
