Alx Sa 59e4aeff3f plug-ins: Use original DDS format on export 
This patch adds a parasite on load that retains
the original import settings of a DDS
texture (such as compression, number of mipmaps,
and flags). This parasite is then checked on export,
and if it exists, we default the compression
format to the original to reduce the chance
the user will choose the wrong format for
the game they're creating the texture for.
The other data stored is not currently used,
but can be implemented in future commits.
