major styling overhaul

custom bootstrap theme (cyti) which is based off of my modifications to
bootswatch's cyborg and has elements taken from their yeti theme too

move around the less a bit to make dev for this style update a little cleaner,
few new helper mixins and what not

revert back to plain markdown instead of markdown2, since extensions are easier
to write for it

restyle notes a bit (not done) and same for phots, still some style bugs
hanging out however
