Modify the way to hook the release of Alt of shortcut keys with Alt

Modify the way to hook the release of Alt of shortcut keys with Alt
to keep the focus from moving to the menu.

Fix a bug where the focus moves to the menu when you release Alt
first when you use a shortcut key with Alt on Visual Studio.

Hook the release of Alt instead of a dummy push of Ctrl on Visual
C++ and Firefox. Hook it on InternetExplorer too.
