This patch changes fetch.php ability to download external files. It now checks
for the returned MIME type and will only download images. For all other
MIME types a redirect is sent back to the browser. This reduces the risc of
being misused as open proxy.
Additionally the download facility is disabled completly by default by setting
the fetchsize option to 0. Users who want the feature need to overwrite the option
in their local.php.
Background: The ability to download external files is needed to resize external
images on the server side. When disabled, a redirect is sent to the browser which
will download the fullsize image and rescale it on the client side which is more
bandwidth and CPU intensive.

This patch adds an option to configure the maximum size for files the fetch.php
will ever download. Setting this to 0 completely turns of the caching of external
media files.
Disadvantages of setting a low or zero fetchsize:
* fetch.php needs to download images to be able to resize them. When the used
fetchsize prevents the downloading the images can only be resized by the
browser which means the browser will need to download the fullsized image first.
* If the linked external media files vanishes it will no longer display in the
wiki because it is not cached.
Advantages of setting a low or zero fetchsize:
* fetch.php may be used for a possible denial of service attack by requesting
many big external files.
* The created cache files may take a lot of space on the server
I recommend to leave the setting at 2MB for internal and private wikis and lower
the setting to about 200 to 500 Kb for bigger public Wikis.
Note: the caching of files uploaded through the media manager is not affected by
this setting.

This fixes a typo which made the new Feedparser not use our own HTTPClient.
It also enhances the get() method of HTTPClient to optionally cope better
with bad HTTP responses:
Some servers return a body with a "304 Not Modified" status which violates
RFC 2616 but is usually accepted by common browsers. Setting the $sloppy304
parameter will return the response body. This fixes problems with feeds
from feedblendr.com

This patch cleans up the source code to satisfy the coding guidelines (see
http://wiki.splitbrain.org/wiki:development#coding_style)
It converts files to UNIX lineendings and removes tabs and trailing
whitespace. Not all files were cleaned yet.

This patch adds an HTTP client written in PHP. It supports proxy
handling and SSL if PHP was compiled with it.
