[orca-list] No longer maintaining Ubuntu accessibility PPA.

[Luke Yelavich <themuso vinuxproject org>]

Hi folks.
I meant to announce this earlier, but got sidetracked. I am no longer 
maintaining a PPA for Ubuntu Xenial with newer accessible packages. I no 
longer run Ubuntu, but I am happy to work with whoever decides to put up 
updated packages for Ubuntu, if they would like any help to do so.
