Change help IDs to reverse DNS style?

[Shaun McCance <shaunm gnome org>]

Hi folks,

Over the last few years, we've moved all sorts of identifiers to the
reverse DNS style, like org.gnome.Calculator. Using that one app as an
example, there's:

* org.gnome.Calculator.desktop
* org.gnome.Calculator.appdata
* org.gnome.Calculator.gschema
* org.gnome.Calculator.svg
* org.gnome.Calculator.SearchProvider.service

But the help is help:gnome-calculator, installed in
$DATADIR/help/C/gnome-calculator/

Should we make an effort to switch help IDs over as well?
