This not only simplifies all the use of _t types to the
ScummVM equivalents, it gets rid of the int32 usage in
favor of just int, solving common type clashes with the
Amiga, for which int doesn't match int32
When ScummVM is built with the new ENABLE_AGS_SCANNER define,
trying to start any game will instead scan all the folders
starting from the current directory downwards, and output
text suitable for pasting in the detection tables.
