Feature: Keybind for movement action complete

[Ryzzenn]

This would allow for behavior somewhere between the Partial Movements toggle on and off. When a token completes its movement action, a keybind could be pressed to end that movement and reset the counter as the Partial Movements toggle does now when a drag action is complete.

This would be useful in the case where users do not always move their token to the final destination of the movement action but still want to track movement easily on a turn where they stride, strike, and stride again for example.

I do like the idea, but I haven't managed to get this working.
