Removed unused bean library
Added trust_html angular filter for unsafe html parsing
Changed modal instructor stats to use cached data

Instead of calling SP and a custom model for each instructor, just pull
the full FTD schedule (which is probably already cached anyway) and use
that for all our stats info.  This also allows inline instructor stats.
Inline instructor stats/cached stats data & new inline charts

- Added page-load schedule load to parse our instructor stats now and
later
- First integrated peity for inline sparklines(charts) but ended up
writing a custom version using plain-css instead
- Now we have graphs that show a 12-month look-back for each instructor
and a quick comparison of teaching hours in FTSS
- Removed all the old modal edit code & SP calls as the data is already
loaded in the $scope so no special handling is required for modal stats
(edit) views
-  Added some rollup options to save space in the collapsed view
