Add a wait_and_hover Sikuli helper method.
Don't click to open a sub-menu in the GNOME applications menu (Closes: #8140).

Just hovering a sub-menu (e.g. "Accessories") and waiting a bit is enough for
the submenu to open. But we did click on it, and if the sub-menu was already
open by hovering, then clicking closed it, of course resulting in FindFailed
exceptions to be thrown.
Factorize starting apps from the GNOME applications menu into a generic step.
Factorize the same as previously, for 2-level submenus.
Look for individual systray applets, to avoid relying on their ordering (Closes: #8059).
Add symlink to make the new apps startup machinery work fine in Windows Camouflage mode too.
