The big purge of the old widget mechanism

Browse Source 
Getting rid of the old widget mechanism files finally gives us a payoff
for all the refactoring. Still a bit of tidying up to do, and we need
to re-introduce the animation mechanisms.

/*\
title: $:/core/modules/widgets/linkcatcher.js
type: application/javascript
module-type: widget
Implements the linkcatcher widget. It intercepts navigation events from its children, preventing normal navigation, and instead stores the name of the target tiddler in the text reference specified in the `to` attribute.
Using the linkcatcher widget allows the linking mechanism to be used for tasks like selecting the current theme tiddler from a list.
