OS Clean & Small Fixes

Added: Seperated the major operating system functions into subclasses (like ProcessManager, FileSystemManager etc.).
Fixed: Some xml structures now look a whole lot nicer.
Fixed: Replaced some ">" id seperators with "-" (">" produces entities).
Fixed: Made some JAXB-methods protected.
Removed MapAdapter

Removed: The map adapter wasn't used in any way, so the utility is no longer avaiable.
