This introduces a new API for the Powerbox, which allows to order its
commands and categories. The order is based on the priority assigned to
the category or command. If two items have the same priority, they are
ordered alphabetically.
To order categories, pass said categories in the Powerbox's params, each
with its own priority. If a command declares itself as part of a
category that was not itself declared, said category will be added
automatically, with the lowest priority.
