Set default language and EDITOR.

Set the default language to use US english and utf8 incase this helps
anything to be more awesome in the future.
Set EDITOR environment variable to vim, if something on the command line
want to make a quick edit to something, I don't want that to launch my
huge emacs setup.
Merge branch 'master' of https://github.com/regnerjr/DotFiles
Updating aliases.

Removed clang alias.
Added svn aliases for seeing the logs from the past 2 days, the past 1
week and the past 2 weeks.
Added an alias for editing the zshrc, cleverly named zshrc.
Added an initial config for tmux.

Configuration is based on the setup detailed in the pragmatic
programmers guide to tmux. (with a few omissions)
Add loading of .aliases, removed PATH modification.

Add a line to load my .aliase file, this helps having the same aliase on
all machines in bash and zsh. Removed a line that was adding some stuff
to my PATH. because my PATH is getting a bit out of control.
Update .tmux.conf

Changed status bar background color to be "default" so that it enables
the backgroud or transparency of the terminal. Set the pane separators
to be a bit more subtle, the active pane is hilighted in yellow,
while the other banes are bordered by thin black.
