Library Changes and Additions

##Filesystem 'filesystem.lua' has minor changes to improve security and integrity of the software.

##Authorization 'auth.lua' is the primary library added to SecureOS. It's responsible for authorizations for the system, login, adding and removing users, ect.

##Hashing At this time, there is only one library for hashing, and that's 'sha256.lua' and is used to hash user passwords without the need for the data card.
