Title: add colour helpers, make midi params order-independent

Nothing big. It just feels a little bit more balanced/symmetric to me this way.

Note: `make-ShortMessage` seemed to be the right place for knowledge about different event representations since it already used `cmd->java-cmd`. Maybe it would be even tidier if `get-metakey` didn't need to know about `midi-shortmessage-command` and instead `midi-handler` transformed `event` into the nicer hashmap representation before doing anything with it.
