libUrl update and documentation

[Dave Cragg]

Hi

An updated version of the libUrl library is available at the following url:

<http://www.runrev.com/revolution/developers/interimreleases/liburl/index.shtml>

Note that this is the same version that is included with the 2.4.3b1 
Metacard release, so there's no need to update if you're running that 
version. However, there are notes on the site about using the 
library, so it's worth a visit.

The new version adds commands for file-to-file transfers:

libUrlFtpUploadFile
libUrlDownloadToFile

Notes on how to use these commands, as well as the exisiting commands 
and functions, are also on the site.

The update also adds a few behind-the-scenes improvements and fixes. 
However, unless you need the above commands, or are having problems 
currently with ftp and http urls, you should be fine with the present 
library.

Regards
Dave Cragg
