New HTTP cookie sample app showing how to use the cookie module

I fixed a few memory leaks in the HTCookie module and added a cookie sample
app to demonstrate how to use the cookie module. Note that the cookie
sample app doesn't store cookies anywhere - this is left as an exercise.

You can find it in the CVS repository as

	http://dev.w3.org/cgi-bin/cvsweb/libwww/Library/Examples/cookie.c

You can find the updates of the HTCookie module at

	http://dev.w3.org/cgi-bin/cvsweb/libwww/Library/src/HTCookie.c#rev2.2
	http://dev.w3.org/cgi-bin/cvsweb/libwww/Library/src/HTCookie.html#rev2.2

linked from

	http://dev.w3.org/cgi-bin/cvsweb/libwww/Library/src/

The MSVC project has also been updated to build the cookie sample app when
compiling the whole thing, see

for details.
