Bump version to 0.4.0

Bump version to 0.3.0

Added forward/backward button functionality

The forward/backward mouse buttons now move through the recent files
list. open() has a new `update_recent_list` parameter to preserve the
order while navigating. Currently only works when clicked directly over
QVideoPlayer due to difficulty detecting global mouse events.
