moved to local copy of bootstrap css/js and better organized loading code and js and css directories
fixed labels in theme.css and added css to better format allowed tags codd in comments (removed white-space: nowrap)
modified comments to use bstart_comment(), to allow finer grain control of how they are displayed. Default behavior is comments are only shown when DEBUG it true. Also has hooks so comments can be echoed without html comment tags (i.e. sans <!-- and -->)
