Replace xfce4-panel with tint

Minimal and out of the way. I've used tint a long time ago (git history should
show thus), apparently it's what I wanted anyways.
Don't highlight individual modules in mplayer
A new layout for htop

The CPU bar graphs are now distributed horizontally instead of stacked up on one
side
Delete a couple of old plugins I don't use

Also, switch to submodules for a couple of plugins. And add NERD Commenter to
the list of installed plugins.
Remove all gtk extensions

Kinda de-ubuntu-fying my configs.
Show workspace name

With tint, there isn't a pager any more. Which is fine, but it means that I'm
losing track when I actually change workspaces or not. So this will at least
keep me aligned.
lyvi configuration file
Update dircolors to 2013

It's been a while. I was wondering why I wasn't getting any custom highlighting
(turns out, the $LS_COLORS was empty! Why? Switching back to
TERM='rxvt-unicode-256color' in 0136a26 meant that my config didn't recognize it
as a color terminal. Derp!)

A while is kinda understating it, since the copyright was bumped up 5 years...
oof. I should do it more often. At least once every two years, come on! Git
history only shows it at almost 4 years of age, so not THAT bad, but if
dircolors gets updated I should probably follow suit.

Oh, and this ends up reverting a1e71d9 / 69a2408.
