Title: Property for enable/disable ALT+F4 combo

In some cases for some application made with monogame usage of alt+f4 is not advisable. By default its true => nothing changes for end user except new public property in GameWindow and nothing changes for platforms without keyboard. This property works on WindowsDX and all OpenTK derived projects but not on Windows8 and does not affect performance.
