Add initial pms-youtube-git and python-pafy-git

First pms-youtube-git PKGBUILD after some prodding by Cirrus. Added
python-pafy-git since it depends on pafy and there wasn't already an
existing PKGBUILD for it.
Various stylistic housekeeping...

Might change tabs to be 4 spaces tho..
Added non-git pms-youtube and pafy
Yay, tags. \o/
Dump...
Renamed pms-youtube to mps-youtube
python-pafy: updpkg
-git PKGBUILDs should have their version set to 'git', otherwise there's just a bunch of useless noise..
gvim-hg: Added Earnestly's PKGBUILD
