Compiling Tge/tgb As Dll

#1 I've compiled TGB as a DLL. Technically, I think you're right about needing only to change the output type. You'll need to make more changes than that, however, for the DLL to be useful.

My changes included the following:

(1) I added a file that exported DLL functions -- to start/stop the engine, to execute an iteration of the game loop, and to expose the scripting interface.

(2) I added helper functions to main.cc to support (1). Sadly, this required copying and pasting code from DemoGame::main(), because the code for initialization/shutdown and running the game loop isn't well-factored.

(3) In winWindow.cc, I commented out the code in Platform::process() for processing the windows message queue, because the DLL is run within the client's process, and I wanted the client to have sole responsibility for processing windows messages. I also added some helper functions akin to those in (2) (more copying and pasting -- grrr...). The helper function for initializing the engine returns the HWND; TGB retains responsibility for creating the window, but the client (Dolphin Smalltalk, in my case) subclasses the window and substitutes its own window proc for handling messages.

Obviously, I'm glossing over the details. Also, I've changed only the Windows code, though I doubt that the equivalent Mac changes would be difficult. I'd like to compare notes with Josh Ritter and find out how he implemented PyTSE (I don't own TSE).

(P.S.: I recently won a TGE license. Otherwise, I wouldn't have been able to respond to this post.)
