#5 A to Z links broken

[Graham Lally]

Clicking on any category in the A to Z results in a 404
Not Found error.

Further analysis indicates this is because the URLs
aren't hex encoded before being displayed.

Steps to reproduce:
1. Go to /ccm/atoz/admin
2. Create a new "Category Provider", setting its Root
Category to "APLAWS Navigation List"
3. Go to /ccm/atoz/
4. Pick a letter and click a link to a category

At first (mouseover) glance, the links being used are
identical to those used on the portal page, which work.
On viewing of source, it seems that the former are of
the form:

http://server/redirect/?oid=\[com.arsdigita.categorization.Category:{id=13315}]

which doesn't work, whilst the latter are:

http://server/redirect/?oid=%5Bcom.arsdigita.categorization.Category%3A%7Bid%3D13315%7D%5D

which does.

Oh, forgot to mention. Tested on Firefox 0.9.1, Mozilla 1.7
and IE 6.0, and fails on all.
