adding an option for an error element to drop error messages into--and handling case of rate limit error from github by dropping it into the error element (if exists) or alerting if no error_el is supplied. Using bootstrap in the demos to create an error alert banner.
fixing grunt file (newest version). upgrading min to uglify and removing jasmine dep until jasmine tests exist :)
remove prettify from demos--not even including js library anyway
