Switched to Zsh and consolidated all aliases

Resolves #21 and closes #30. Combined all alias files, converted them into
proper Zsh formatting and reorganized them into better sections.  Installed Oh
My Zsh and then sourced the combined aliases file (zsh_aliases) from .zshrc.
Also made URL's clickable in urxvt and briefly commented purpose of all Vim
plug-ins.
