The wide coverage demo apps now shows a "please wait" message while the grammar
is loading, and a red error message if the grammar is not found on the server.
The Simple Translation Tool also show red error messages if the grammar is not
found.
Also improve behaviour for languages that are missing in Phrasebook (Chinese).
Also update the initial set of languages in the menus to match Translate11.pgf.
For example, you can now reorder paragraphs by cut & paste, without causing
anything to be sent to the server for re-translation.
Also some color & layout tweaks.
The layout now resembles a certain other online translation service.
The translation is started automatically after text is entered, no need to
press the Translate button.
The background color of the translation changes to pale green, yellow or red
according to the quality.
Two types of quality indications are supported:
+ From the grammar: linearizations starting with "+" or "*" are assumed to
be of high or low quality, respectively.
+ From the parse tree: if the root function is "?", then the translation is
assumed to be of low quality.
If no quality indications are detected, medium quality is assumed.
+ PGFService.hs: add command c-grammar, include probability in parse results
+ js/gftranslation.js: add start position and limit parameters, return more
info to applications
+ Simple Translator: show two wide coverage translations
+ Wide coverage demo: show parse tree and probability (intended as grammar
debugging aids)
