Patch to resolve issue

User starts to 'Save Playlist' using 'Save Playlist' option in extras menu,
but then chooses to back out without actually saving playlist.

This generally breaks the ip3k menu - screen will go blank. I am also
finding that I usually (always?) need to restart the server in this
circumstance.


This appears to be an unintended side effect of:
http://svn.slimdevices.com/slim?view=revision&revision=29149.

Refer bug #15001, which was reopened as a result of this breakage.
(Comment #12).

That revision introduced an additional 'popModeRight' which is executed
when the playlist mode is exited. The mode may be exited either after saving
the playlist, or as a consequence of the user backing out.

In the latter case, the effect is now to back up one more level than is
actually required. This breaks use via the extras menu, which is only
two 'popModeRights' from the Home menu. Removal of one 'popModeRight' from
'savePluginCallback' 'backspace type' was also required. 


The attached patch resolves the issue on my local LMS.
