Add support for comments in JavaScript annotations

[p4t5h3]

Translation comments are only supported when using the v-translate directive or <translate> component but not for plain JavaScript annotations. To add support, I thought about two options.

The first is extending the existing functions with an optional parameter like this:

vm.$gettext(msgid, comment = '')
vm.$ngettext(msgid, plural, n, comment = '')
vm.$pgettext(context, msgid, comment = '')
vm.$npgettext(context, msgid, plural, n, comment = '')

The second is probably more complicated during parsing:

vm.$gettext(msgid) //. comment given by the programmer, directed at the translator

The syntax above is derived from GNU gettext utilities documentation. The comment may appear in the same or previous line of the annotation.

I think the first version is way more explicit, and we'll run into less false positives.

The drawback is that translator comments become part of the runtime although they are only needed at build time to generate the catalog (right?)

[vperron]

Sure, but that's how it works in many other languages and implementations.

Fine with me :-D
