[orca-list] Updating the Orca Wiki

[Steve Holmes <steve holmes88 gmail com>]

I took a stab at updating the download/install page yesterday by 
correcting the link for pulling the latest source.  The original text 
still had reference to the svn archives so I figured to insert a link to 
the git repository.  I used the wiki instructions to insert a link by 
seeing that [[ ]] surround the git address.  Well, not bad for a 
beginner, but I noticed that "http://live.gnome.org:"; got prepended to 
the frunt of the link I inserted.  Does anyone with more wiki experience 
than I know what I might be doing wrong?

Thanks, and look forward to helping out more with the docs where possible.
