Javascript files are not checked for left out files

[Claude Paroz]

With intltool-update -m, Javascript (.js) files are not checked if they are omitted from POTFILES.in. Now that GNOME is using more and more Javascript, this is becoming a crucial issue (see e.g. https://bugzilla.gnome.org/show_bug.cgi?id=613092). I suppose the fix is only an addition to the $buildin_gettext_support variable.

I agree this is important to fix, but it's not that easy: JavaScript files are not natively supported by xgettext (i.e. try creating a JS file with a single-quoted string), so that's not going to work. We'll probably have to pass a suitable xgettext -L option for them, but ideally, someone would add native JavaScript support to gettext.

gettext supports JavaScript since 0.18.3.
