AWM: Moving autostart back into awesome

Crunchbang doesn't seem to make use of the .xinitrc file, so I'm moving
some of that functionality back into AWM by way of a shell script.
AWM: Autostart configuration

Been hacking on autostart and rc.lua to get the desired start-up
sequence. I'm not quite there yet, but I'm getting a lot closer.
Bash: clean-up

Cleaned up the bashrc and bash_aliases files. Reorganized each a bit as
well.
Deleted x

Since moving into crunchbang, the x/xinitrc responsibilities have been
handed back to AWM, thus making these files obsolete.
Slim: Added slim configuration file

Created the associated rake deployment task as well.
Bash: changed some bash aliases
Added 'remaster' task and files

Previously the 'remaster' work was done by a shell that I kept in a
different repository, but it didn't make sense to store that script
separate from my dotfiles, given that I'll always need both at the same
time. Thus, I've merged the projects.
