Advanced parenthesis patterns (and they're Actions now)

[Robotgiggle]

Adds Interjection, Meditation, and Recollection to allow more advanced pattern-list building.

• Interjection (used while introspecting) reads from the offhand and inserts the resulting iota into the in-progress list.
• Meditation pops an integer and opens a list to the specified parenthesis depth.
• Recollection closes a list from any parenthesis depth, pushing the depth and the list.

Meditation is treated as a normal pattern when inside existing parentheses because there's no way to determine how many new layers it should open. This is kind of a janky solution, but the only alternative would be to prevent using it inside parens altogether.

Recollection pushes the list on top of the depth for convenience, since you're much more likely to need the list as an argument for something (saving it to a focus, adding something with Integration Distillation, etc) than the number.

FYI, I'm not entirely satisfied with the patterns for Meditation and Recollection - they're kind of awkward to fit into the grid when you have a bunch of other stuff. Recommendations would be appreciated, though make sure to avoid conflicting with stuff like Open/Close Transmit from Hexal.
