Subject: syntax/dome_key.vim: Add more detailed `map` highlighting

This only works for `map` definitions, but I'll be using what I've
learned here for the other map types.

* Only highlight `map` if it's on the start of a line
* Only highlight `<Up>`, `<Play>`, and `<Down>` in map triggers
* Highlight any special key in map actions
