Tries to Play Directory When You Click the Play Button When You have Select A Directory

[Joshua Eichen]

Elisa tries to play a directory when you press the play button while you have a directory selected. Right now they loading animation plays forever, but we should pick some default behavior.
Some suggestions are:
a) Nothing and/or an error message.
b) Play first playable file in the directory
c) Goes into the directory

We need to pick one and write the expect behavior case.
