Tmux sess auto-attach; vim compile-sass fxn.

Add:
	vimrc
		-add key-mapped CompileSass(), which calls the `sass` utility to compile
		the .sass file in the selected buffer to a .css stylesheet with an
		identical name (eg, app.sass > app.css).

	bashrc
		-soften hard-tabs preceding the comments following every color
		escape-code, for portable alignment across lines.
		-add conditional to immediately attach to any existing tmux sessions,
		and create a new one if there aren't any.

	tmux.conf
		-add keymaps for resizing panes at increments of 4 units.
