Description

Adds additional key bindings for the following interactions:

Key Binding	Action
Space	Show the next line of dialogue Transition out the location notification
E	Enter and exit the Explore mode
V	Enter and exit the Move mode
T	Enter and exit the Talk mode
Numbers	Select dialogue topic under the Talk mode Select location under the Move mode

UI changes to let the users know there are keyboard shortcuts available:
