#129 Keyboard events in windows with multiple panels

[Sylvain Loiseau]

In the Global preferences and package preferences windows, the list on the
left is linked to different set of options displayed on the right.
If the focus is on the list on the left list and that I navigate with
the up and down arrow keys, the selection does not change the set of
options on the right. Only the mouse action triggers an update.

Maybe the same issue in Mode preference and File mapping.

[Bernard Desgraupes]

This is fixed using the tableViewSelectionDidChange delegate method for table views.

Changes committed to the repository (rev. 1329 (sourceforge.net)). The core must be rebuilt.
