[Interwiki] quick wikigateway update

[Bayle S. <bs...@uc...>]

Changes:

* MediaWiki support is in CVS.

* a primitive "wikicp" command for copying wiki pages (but no markup
translation yet!) was in the last
(April; .00196) released version.

* WebDAV support (for the client-side) was in the last released version


Summary:

So, currently, if you
have any of these wiki server types:

* OddMuse
* UseMod
* MoinMoin
* MediaWiki
* Or any WikiRPCInterface-supporting server

then a client can, via WikiGateway, read and write to the wiki using
any of the following methods:

* WikiRPCInterface
* Atom
* WebDAV
* Python module
* Perl module
* Command-line client

It's likely that support for 2 more wiki servers will be added in the
next couple of months (although if people want to help out maybe we
could do more)
