[scaladoc] There is a text filter tool for members (searching on member
name and comment body). Adds button to reset text filter tool. No
review.

Known limitation: filtering of members is blocking on keystroke leading
to sluggish performance on large classes. Scheduler from index needs to
be used for member filtering.
