Add edge-guides for horizontal gravity lines

Browse source 
These visualize the horizontal gravity line kludge for rooms beside
eachother. When you enter another room, gravity lines which look like
they're connected between the rooms try to have the same activated
state.

Basically, if you're in room (1,4) and you go into (2,4), if a
gravity line in (1,4) is activated (gray, on cooldown) and it's
touching the gravity line in (2,4), that gravity line will also be
activated.
