Drop OSX support; support desktop, laptop, cloudtop

Dropping support for OSX. Moving forward these dotfiles will depend on Linux
systems. Furthermore, since I'm support a ~/bin, the machines that consume these
dotfiles depend on i386 architectures. Linux and i386 are two dependencies that
I'm okay with since the leverage this assumption provides, makes their existence
tolerable.

There is some Google leakage herein, which includes aliases, functions, and
mentions of cloudtop. For now, this is okay. I may break the Google specific
code into its own repository, but for now, this is less maintenance.

This also introduces a ~/.profile instead of erroneously defining environment
variables in my zshrc file, which was unadvised.

This is a large commit and also introduces new aliases, variables, functions
that I accumulated over the past week or so while migrating away from OSX and
onto my new setup. Hopefully in the future I'll be more precise with my commits.
