Secured Signing Electronic Signature service: added Custom Options

Secured Signing Electronic Signatures now support a custom options field. This is intended to support additional options released by Secured Signing in the future and allows for those options to be included in Documents without requiring a code change first - it is likely that full support in code would follow later.

Documents now support the constant "SecuredSigningCustomOptions", where you can specify custom options.
