Change to use ProtectionSystemSpecificInfo. 

* EncryptionKey now contains them rather than a PSSH box.
  * Outputs PSSH boxes for each entry.
  * Outputs a ContentProtection element for each entry.
* Removed SystemName and UUID from KeySource.
* Removed --scheme_id_uri packager argument.

Issue #88
