temporary workaround for <doc> bug

It turns out that doc tags aren't supported be the core, despite the 
claims to the contrary in bug 190. I have patched the widgets archive to 
delete all <doc> tags. It can be pulled from:
http://darcs.smallmerchant.com/ibex_widgets

The patch is called:
TEMPORARY deletion of doc tags from widgets until <doc> works. Unpull 
this patch once it has been fixed

With this patch applied, Charlie's widget test suite loads without 
errors. Unfortunately it loads (for me at least) as a zero sized window 
that isn't resizable. Various (max|min)(width|height) parameters hand no 
effect.
