[ZWeb] Left Nav Headings

[Chris Withers]

The headings in the left nav currently go to pages, such as:

-Documentation
-Download
-Developers

At best these are unmaintained re-hashes of content from within the 
category (such as /Documentation).

At worst, they point to one of the sub-categories (such as /Products).

How about just having these as un-linked category headings?
It eliminates the need to maintain those pages, which on it's own can't 
be a bad thing, and might also make the left nav more readable (less linkz)

cheers,

Chris
