Added a regression test which validates that keystrokes are received correctly in ChromeFrame. We specifically

test for uppercase characters generated in combination with the Shift key. 

Added a helper function to explicitly give focus to a passed in HWND. This is done by sending the mouse move/mouse
down and mouse up events to the window. We also use this in the AboutChromeFrame test, which was flaky at times.
