fix for #146046. fix several regressions to the subscribe dialog.

1)  [search view] "Subscribe" and "Unsubscribe" buttons don't work (original bug)
2)  [search and tree views] space bar doesn't do the right thing (toggle state)
3)  [tree view] double click on a row that is a container should not toggle the subscribe state
