Adds kmdecomp to kmcomp-<version>.zip and fixes a couple of stability
issues:
* Increase buffer sizes (this fix very much a hack)
* Ensures that .bmp/.ico files are saved to correct output folder
* Disable loading sentry.dll when running on WINE
keyman64.h is now only used by keyman32/keyman64. Shared components have
been moved to legacy_kmx_memory.h - KMX structures in-memory, as used by
kmanalyze, kmdecomp.
Removed unnecessary references to keyman64.h from kmtip.
Also removed aiDebugger.* which are obsolete files.
One day in the future, we could merge keyman64.h with keymanengine.h.
