Comment 1 for bug 968556

Pushed a rebased branch that includes an extra commit to add a "Simple" flag to value maps. This pushes things to the top of TPac lists. JSPac currently ignores those entries.

The idea is to use comma delimited code lists to "group" things. If you are keeping all the specific entries for advanced users you flag the grouped entries as "Simple" and they show up at the top of lists in TPac. If you are grouping things to reduce the length of lists you just hide the single entries with the opac visible option.

This basically ends up reproducing the "Simple/Advanced" views from JSPac with simple above a divider and advanced below it.

It also fixes an excessive escaping issue that was causing things to not match from TPac.
