Added the feature to allow creating a TAS movie from a save state. To activate this function, start the game and use the "Start recording" command. A save state will be created at that point in time and the emulator will start recording. This results in two files, a .dtm containing the movie and a .dtm.sav which is the save state.

Changes:
* Allow events to be scheduled when the emulator is not running.  This allows the save state event to be added before the emulator starts.
* Removed the Audio back-end init flag from the save state.  This value should not be saved as it is not data relevant to guest machine.
* Allow a recording to be started at any time (apart from when a recording is already being made).
* Updated the status bar and title bar when an on-screen message is shown
* Removed the saving of PEToken from the save state as the FIFO will save this information
* Added a couple Pixel Engine interrupt states to the save state
* Added the copyright notice to the GCPadStatus.h file.

This function is preliminary.  Let us know of any bugs you find or any UI quirks.
