Implement cas encrypted attributes decryption

[dgeo]

I'd love phpCAS to be able to decrypt attributes from CAS server > 4.1, http://jasig.github.io/cas/4.1.x/integration/Attribute-Release.html#encrypting-attributes
It would mean (as well as I understand):

• using some private key stored somewhere
• dunno how to detect which attributes are to be decrypted (specify list with private key ?)
• expose a function to decrypt attribute, or transparently decode them

Unfortunately, I miss time and skills to propose a useable patch here, it's just a whish for now :)

I don't know if it helps but there's a setCasAttributeParserCallback which you can pass your parser/decrypt class to (in master branch).

See 9376b31

I'd think that this is to be included in cas protocol, it'd have been nice to have the cas library take care of it :)

Anyway, thank you for the pointer, I'll keep in mind for the next time I need this.
