DRC dialog session confuses GAL router state

[Dick Hollenbeck]

Regression: GAL mode, with track tool selected, run DRC. Although the toolbar icon reverts properly to non-track mode, i.e. vanilla arrow mode, the router internals remain in track layout mode. You can lay down track after dismissing the DRC dialog, even though the track tool is not visibly selected. This bug existed some time ago and was fixed, now broken again.
