Wrote GetOpt.hs for parsing cmd line options
Added command line option support

-h specifies the MPD host, -p specifies the MPD port. If "-q qry" is supplied,
then the query will not be read from stdin, and "qry" will be executed insted.
If the -f switch is supplied, the user will not be shown a list of videos, and
the first video will automatically be played.
