Update the installer for Mistworld.

After some time cussin and spittin tobaccer juice, I've gotten things
somewhat working.
Namely:
* Set the WINEARCH to win32 (it was thinking the game was 64-bit)
* Setting the WINEPREFIX to the new path to reflect architectural
changes.
* Removing the unnecessary call to install SAPI.

The notable problem was that for whatever reason the compiled
nvdaControllerClient32.dll the manager was fetching did *not* work
with the game. It complained about testIfRunning not being present in
the compiled executable, which it certainly was.
If you have a spare copy of the DLL lying around that works you should
back that up and if you switch to the testing branch copy it *both* to
AGM cache and the game directory.
