world.js: Trigger movement with clicks on the map

Browse Source 
Clicking on the map in different quadrants will move you in that direction.
Clicks are measured relative to the centre of the current location centre of
the map. Click above the player to move up, click below to move down etc.

This should enable better gameplay on touch devices.
