Bug # 1 - Changing themes break Layout

[kabua]

Using: VS2013 Test Changed: ToolViewModel's _isVisible = true; to false;

1. start app (notice no Views are selected or showing)
2. Change theme
3. Click View > Git Changes

Error Git Changes doesn't show up.

Expectation The Git Changes should show up in the right-hand tool well.

Another related issue The Views that are docked take a long time (1-2 seconds) to be shown. Perhaps related to why the tool-well tools don't show up.
