Fix Google Translate button initialization

Notes: at MT init time, the targetLanguage member seem to be missing; the target language is now taken on editor "ready" event, when it is gathered from <textarea lang="..."> attribute (there should be a cleaner way to store and retrieve the source and target languages than it is now). Also: was there a reason to store the 'targetLang' as a propery of the plugin? I removed that code. Especially now that the target language can be different across units.
Partial pick: Visually emphasize the rendering of non-zero 'need translation' and 'suggestions' values

Pick note: It is not necessary to pick the rest of the changes since they

--cleanup option no longer deletes projects

According to docs: "Using the --cleanup command line option, languages added
to projects that no longer have matching files on the filesystem will be
deleted.". However, the code would not only delete missing languages in
projects (aka "translation projects"), but would also delete projects
themselves. This has proven to be troublesome. For now, the --cleanup option
will only affect translation projects. One can imagine a separate explicit
"--delete-missing-projects" options to unregister projects as well.

Pick note: Wrapped the description above so the line doesn't span forever,
because commit messages must be readable.
