Functions to export/import player verb state to a buffer

[LastLifeLeft]

Is your feature request related to a problem?
In a multiplayer with rollback or a rewind feature, we can't use Input easily because it doesn't allow the user to manage its current state.

Describe the solution you'd like
A pair of functions to save and load the current verbs' state, so they can be accessed normally.

Describe alternatives you've considered
I could write some sort of communication layer between my objects and Input, and then save its state rather than the state of Input itself?

Additional context
I like ponies.
