Adding basic bash scripts for systems w/o zsh

I've decided that a minimal bash config that I
feel comfy in is both (1) good to have around and
(2) a good learning experience about the terminal!

I've done a good bit of "best practice" research
for putting together these files (specifically
bashrc vs bash_profile...).

For now, I'll continue to use oh-my-zsh because of its
awesome interactive features!
