MDL-40006 searchableselector does not work in IE or Safari.

This fix is a horrible hack, but one I have used for years in tool_editrolesbycap
https://github.com/moodleou/moodle-tool_editrolesbycap/blob/master/yui/capabilityformfield/capabilityformfield.js
and it seems to be reliable.

As an added bonus, I removed the use of YUI2 here.

Also, I fixed the related button in quiz to be GET not POST.
