map controls

[Hugh Latham]

It would be very helpful if the map zoomed from the location of the cursor. Currently it appears to do so from the center of the screen and then suddenly shift the map downwards, which offsets it from the position of the cursor as the zoom progresses.

At some point in refinement of the ui the map should become a better information tool perhaps including some of the following:

1) Placement of a dot under the cursor

2) Highlighting ones outposts

3) Plotting courses with the cursor
