simple translator: Replaced 'GF Robust Parser' with 'GF Wide Coverage Translation'

Browse Source 
The interface to the wide coverage translation is in js/gftranslate.js
and it assumes that the grammar is installed on the cloud server
as /robust/Translate8.pgf.

The list of supported languages is hardwired in gftranslate.js, since
there is no support for obtaining this info from the C run-time system
at the moment.
