Depreciated InputManager.getSimluateMouse and replaced with InputManager.isSimulateMouse for consistancy.
Removed depreciated TouchInput.getSimulateMouse().
Added InputManager.isSimulateKeyboard() to keep consistancy with mouse methods.
Also changed JmeAndroidSystem to store the view instead of the activity.
When users call JmeSystem.showSoftKeyboard(true), the default Android soft keyboard is displayed and any key presses are sent to jME as touch events. Key events are also generated so the user can use the same key listeners as Desktop to keep the user code common between Desktop and Android platforms.
