This clears up much of the todo list for mspatcha. GetFilePatchSignature* and NormalizeFileForPatchSignature have now been implemented in these changes.
These changes bring better support for things like the Adobe Acrobat installer without the need for things like the winetricks mspatcha.dll native dll override. Still needed is support for interleaved streams in the LZXD decompression logic, however this is a great start to better supporting software installers that use the Windows interface for creating and applying patches to files.
