[express-devel] http commit

[Brian St . P. <bst...@me...>]

The commit from tonight enables express to load pages that are sent with
a Transfer-Encoding of "chunked".  I also put in a little (very little)
better checking so that we can pick from one of a few different ways of
reading content from the server, according to the http headers.

There are still some crashes.  The biggest one is from an assertion when we
try to load an image that doesn't have an absolute URL.  I will try to
fix this soon, but if anyone else wants it:  the fix neds to go into browser.c,
in browser_load_image().

slashdot loads better, but you won't get past the front page (see bug above)
yahoo loads pretty good
sourceforge is unloadable (see bug above)
express.sourceforge.net works ok, screenshots won't show up (see bug above)

Obviously, fixing the image-loading bug will be my next priority...
