Subject: SI-4887 Link existentials in scaladoc

Based on an inital patch by Nada Amin. Rewrote some of the code to
compress it a bit.

Also fixed a problem that was affecting the prefix printing for
typerefs: type parameter and existentials won't get prefixes. While
I can imagine cases where you'd want to see where they come from,
you can always hover over them and see their origin.

Also added support for pretty-printing ThisTypes, SuperTypes and
SingleTypes (with links)
