Christoph Oelckers 7661720585 - fixed Blood map loading 
Whoever designed that map format with its idiotic encryption should burn in Hell >)
It's a needless complication and open invitation for errors.
To avoid follow up problems it now uses its own local struct for loading in the sprites and the global spritetype no longer depends on any map format and can be changed as the need arises.

Fixes #101
