Throw an error message when $WORKON_HOME is not set

Fixed output issues webith websearch plugin.

- if user has rm set as an alias to 'rm -i' user is prompted to whether to
  remove the nohup.out file.

 $ ddg fools
	nohup: ignoring input and appending output to ‘nohup.out’
	rm: remove regular empty file ‘nohup.out’?

- if output redirected to a file nohup will not create nohup.out and rm is
  unecessary.
Add itunes shuffle command to OSX plugin.

Added shuffle functionality to the itunes command in the OSX plugin.
iTunes 12 doesn't support setting the "shuffle" property on the playlist
from what I've read, so this simulates the user interacting with the
iTunes interface. The toggle option "clicks" the shuffle button in the
Now Playing area. This has the effect of toggling the shuffle setting on
whatever is currently playing. The on and off options use the Shuffle
menu bar items.

Usage: itunes shuffle [on|off|toggle]
