#26 Drag and drop function

[asterios mpakavos]

Hi,firstly i would like to tell you that OpenSebJ's interface is so helpful and clearly
built,that even a novice user can accomplish all of the features provided. I think that
except for the "add" button above the track,it could be very useful for the user to drag
a sample from a folder and drop to track. Do you think that this feature would be
useful/helpful for OpenSebJ?
