Update README
Markdown README
Update README
Fixes ad changes.

Fix error when -r is not specified.
Mplayer output properly displayed
Couple of change to help output to make it clearer.
Convert position, exit if it cant be converted
Implement new method to control the player using fifo.

The player is started with an open fifo pipe for control, after which
the current playing file is detected and an entry is added to the
resume-cache file after its done playing

Since mplayer has to be started before we give it any option the fifo
pipe is used to seek to the last location instead

the advantage is that all arguments including filename are passed
directly to mplayer now.
Reset playback position when reaching EOF
Update README
Use absolute filename in cache.

Absolute filename used in cache so you dont have different entries for
different paths.
Also fixed problem with some videos outputung their location in a
differet output.
