Sets various documentation strings on this:
* blurb is used for instance as the this's tooltip when represented in the UI such as a
menu entry. * help is a free-form text that's meant as additional documentation for developers of scripts and plug-ins. If
the blurb and the argument names and descriptions are enough for a quite self-explanatory procedure, you may set help
to null, rather than setting an uninformative help (avoid setting the same text as
blurb or redundant information).
Plug-ins are responsible for their own translations. You are expected to send localized strings of blurb and help
to GIMP if your plug-in is internationalized.
