update config to point to bootstrap
fix some loader stuff; make google analytics work - mayb:
updates to GA tracking
update curriculum, remove some css, add library functions
add unused css, symlink progress gif
curriculum seems to work; course is broken tho
fixed course loading
remove logs for course.js
update HTML pages (topic, empty) to use only loader

fix a typo in course.js
Refactor topic loading to be more generic

Topic.js is now loader by loader.js
topic html pages now only make a call to loader.js
topic.js checks to see if it should do anything
-- currently this is a waste for non-topic pages but that can be fixed
(we should have a build system anyway...)
this also moves more things to using classes for .full (and llab.selectors.full)
i fixed a llab.fragments.bootstrapSep reference issue
