Merge pull request #89 from Nekotekina/master

...
First installment of RPCS3's custom crypto engine:

- Removed all scetool dependencies;
- Implemented a key vault to manage PS3 keys internally;
- Implemented SELF decryption;
- Improved PKG handling.

Notes:
- NPDRM SELF files (EBOOT.BIN) can also be decrypted. A valid matching RAP file must be placed under the dev_usb000 folder.
- The source code is considerably commented and several debugging functions were also added in order to aid anyone who wishes to contribute to the engine.
