Significant changes to the Encryption library
- Removed double-encoding with XOR scheme when Mcrypt is available. Additional obfuscation was not significantly aiding security, and came at a very high performance cost. - Changed the default encryption mode from ECB to CBC for much improved security - Added an encode_from_legacy() method to allow re-encoding of permanent data that was originally encoded with the older methods.
