The help message for /help <command> was using the translated/aliased string,
which meant that you had to have a usage translation for each command alias.
This became unmaintainable in Project X, where we had artists adding emotes
with lots of aliases, and I'm guessing it was booched in the Y!PP translations,
since they seem to lack translations for things like m.usage_escuchar. Let's
instead use a usage message based on the untranslated command, then compose
the actual command used into that (for aliases). This should be mostly
backwards-compatible, but I will be updating Yohoho and Bang in addition to
Project X: this involves replacing the command name in the usage translations
with {0} and returning getUsage(command) instead of "m.usage_blabla".
