* add module_from_xml param to I4xSystem * use it to implement xmodule.get_children() * fix a few comments here and there * Render-time progress display for seq and vertical modules. - Computes fraction of subproblems done. * Pass problem state back to js during ajax calls. * general cleanup in capa_module.py * add progress_changed and progress fields to json returned from each ajax handler * Coffeescript changes to hook up sequence tracking of problem progress * net result: sequence 'a' tags now have a progress class * properly set css class on initial load * fire event when progress changes after ajax calls * also save state in 'progress' property of problems-wrapper tag * event handler finds those tags, computes updated progress
