RSS feed manipulation is alive

[Daniel Sheppard]

Bah, bugs abound.

This fixes the mime-types and also no longer barfs when it tries to
parse a page and it can't. 

Mousehole laughs in the face of partial-content feeds.

Bah, it seems every time I make a post anywhere this week, it's followed
by a correction.

It's currently only picking up the application/xml and text/xml mime
types - if you want application/atom+xml, you'll have to edit line 29.

 <<fix_xml.rb>> Requires some fiddling. You need to require the fix_xml
in your mousehole launcher, this provides:

- the ability to manipulate RSS/ATOM feeds
	- only for application/xml+atom and text/xml mime types
	- all output will be as an ATOM 1.0 feed

- the ability to cancel the manipulation of a page by raising
MouseHole::CancelRewrite
	- this allows you to decide whether or not your script should
execute from within the script.
	- helps to avoid both the overhead and error potential of page
reconstruction.

Then you can use the attached "Atomic Mouse" user script, wherein you
enter in an RSS/ATOM path and an Xpath for extracting from the
full-content page to create a full-content ATOM feed. The script will
cache page content so that you don't incur the wrath of an angry
webmaster. The cache is cleared upon modification of the xpath rule -
I'll probably change it to also keep an eye on the last updated time on
the feed entry as well.
