Subject: [PATCH] [autotests/integration] Test basic working of Alt+Tab and
 Alt+Shift+Tab

Dedicated test methods for Alt+Tab and Alt+Shift+Tab. Both open three
windows and simulate one press with opening the TabBox. Alt+Tab should
move to the previous window in the chain, Alt+Shift+tab to the last
window in the chain.
