In db110f78, IDC_EXIT was changed to be
handled by Chrome instead of Ash. This reverts that change.

Originally, I thought Chrome would have to register the IDC_EXIT command
so that menus would show that shortcut in the relevant row. However,
the Exit command isn't shown in the Chrome OS app menu so it should be
fine to skip registering it completely and let Ash handle it.

Also verified that ctrl+shift+q is still treated as reserved, i.e. cannot
be eaten by a webpage. This site is useful for manually testing that:
