jsgettext FC

[craigh]

need to figure out how to deal with {pageaddvar name="jsgettext" value="module_news_js:News"} going forward.
Not sure it ever properly worked in the first place.
translation for >=1.4 is different anyway and JS translation must be accommodated.
refs #2487

currently pageAddAsset() doesn't allow jsgettext so it is filtered out and set as a pagevar instead. Obviously this is wrong, but the system won't work in twig anyway, so it probably doesn't matter until a solution is implemented in general.

maybe a duplicate of #2487
