Designed to facilitate playing keyboard-only on a small screen.

Overrides the existing scroll lock process.

Adds a third state to scrolling, the 'hunt' mode.

Press scroll lock once to enter 'hunt' mode,
Press a movement key to move the camera to the indicated octant, exiting 'hunt' mode, resuming movement.
Press scroll lock again to center on the character and then enter a 'scroll' mode similar to the original but with larger scroll steps. In both places, rest centers upon the character.
Press the scroll lock a third time to exit 'scroll' mode and resume movement.

Its easier than it may sound.
