When dwarf is selected, up/down arrow should change dwarf selection, not Group By selection

[GoogleCodeExporter]

Version: 0.5.6

Steps:
- Click on a dwarf in the grid view pane to select it
- Hit the up/down arrows on the keyboard

Expected result:
- DT changes the currently selected dwarf in the grid view

Actual result:
- A different setting is selected in the Group By dropdown

Other:
Ideally, it should be possible to select rows via up/down and columns via 
left/right and set/unset labors via the spacebar. This can be less tedious 
and/or more accessible than mouse clicking for some people.

Agreed on both counts; I was also expecting up/down arrows to change the Group 
By selection. And being able to navigate the profession grid with the keyboard, 
or else using Shift-click to select a whole row to change at once, would be 
nice -- I often want to turn off (or turn on) ALL hauling jobs for a single 
dwarf, or even a whole group of dwarves. It would be nice to be able to do that 
in just two clicks.
