Subject: [PATCH 1/3] handle more complex ruby from/to html - fixes #605
this is not exactly great, but it should be "good enough"
note that the new `group` function should not escape in the wild, as
we don't document it and only use it internally
I tried using `$[scale foo bar]` instead of `$[group foo bar]`, but
that would be rendered as `foo bar` when sent over the network
to non-misskey instances, and we don't want that
