Ability to toggle Datapad zoom state

When the player is not moving and the datapad is brought up, it will go to a fully zoomed position, which even removes the helmet HUD elements from the screen, and the datapad screen fills the entire screen. While in some cases (such as when reading text) this zoom level is the best, it would be nice if the "Zoom" control would toggle the datapad between this state, and the "full view" state when the HUD is also visible while the datapad is a bit further away and in full view. (Currently the "Zoom" assignment in datapad control mode doesn't appear to be doing anything.)

It would also probably be better if the "full view" would be the default state, and using the "Zoom" control would toggle it into the fully zoomed state and back for the times when the player wants ro dead something up close.
