[Bug-XBoard] Help for accessibility.

[Gabriele Battaglia]

Hi dear team.
We are a comunity of blind people and we'd like to ask to add some 
accessibility feature to XBoard.
There is no accessible software to play chess at a certain level or 
throw FICS, on Linux and Mac computer and XBoard is totally not 
accessible to VoiceOver tecnologies.

Thanks if you can consider make an accessible version.
Gabriel.
