[jokosher-devel] [PATCH] import selection of audio

[John Kelly <kelly_worth2003 yahoo co uk>]

This patch will eventually add the ability to select the amount of audio
the user wishes to import in minutes and seconds. At the moment, only
the gui is done. The gui looks acceptable but it probably could look
better.
