[CFT] New upstream snapshot of mplayer and mencoder

[Thomas Zander]

Hi folks,

I have prepared an update to our ports for multimedia/mplayer and mencoder.
You can find the drop-in replacements (just extract it in
${PORTSDIR}/multimedia) at this url:
https://people.freebsd.org/~riggs/m20140815.tar.xz

Changes
- Update to recent snapshot (2014-08-15) of mplayer and ffmpeg.
- GUI is no longer default OPTION. My perception is that most users
use mplayer from the command line only or through 3rd party UIs. Let
me know in case this is not true.

Feedback is appreciated, as always.
Best regards
RIggs
