 Attached patch contains a proposed template function to produce a list of
 all the registered activity types for use in a <select> element, or as
 <input type="checkbox">.

 When working on turtleshell, I wanted to add filter controls to the
 activity directory, just like how BP-Default has a dropdown box.
 Unfortunately, these are hardcoded into the BP-Default templates. We
 already register activity types, but we don't have a template function to
 output the data.

 My patch implements such a template function and allows choice between
 rendering the activity types as a dropdown box or as radio buttons.
