Simplification of one-instance mode 

It now checks if a capable "Media Player" is running, not only VLC.

# NOTE: this controller is a SAMPLE, and thus doesn't implement all the D-Bus Media Player specification. http://wiki.videolan.org/index.php/DBus-spec
# This is an unfinished document (on the 12/06/2006) and has been designed to be as general as possible.
# So don't expect that much from this, but basic capabilities should work out of the box (Play/Pause/Next/Add)
#
# Also notice it has been designed first for a previous specificaiton, and thus some code may not work/be disabled
