Clean up mode selection in map options menu

[GoogleCodeExporter]

The current mode selection interface in the map options menu is confusing:
- Selection mode
- Panning mode
- Zooming mode
- Fit-to-window mode
should be reorganized as drop down options from a Mode item. This needs to be 
coordinated with the revised zooming and panning operation (see also #22, #114,
and #147)

Update solution in ci 3678:

The design is not allow to add toolbar for map in one place. So, have to add 
toolbar code in every other Map views, e.g. LISA, G/G*.

Will still be in 1.7.35, a new build will be created.

will replace "zoom" icon in toolbar with two separate icons: "zoom in" and 
"zoom out". 

since it will impact the code with key code, will also add a "brush" icon, so 
that user doesn't need to hold Cmd key to enable brushing feature
