Update airline theme to match
Add new airline style tmux line & reference in tmuxconf

Themes aren't synced so its currently hardcoded to Tomorrow in a sense
Setup git submodules & an rcrc

Antigen is a dependency I have 100% so its now a submodule
of this repo so automatically have it.

Also setup rcrc so certain files are ignored when rcm is run/setup
because shit like readme & terminal theme don't and shouldn't be
symlinked nor should i have to remember i have that shit.
Add tmuxline to bundles & font replacements

Apparently terminal doesn't understand the default characters
so replacements have been set so it doesn't look like shit/ eagle characters
