The decryption should happen transparently, also, resolver should not decrypt for itself only, whole maven should have access to all.
This PR also disables Maven 3.0 IT MNG-4459 as Maven4 stops with this "security through obscurity" (keep encrypted pw in memory kinda for "security reasons" but in reality any mojo or extension can decrypt anything they want).
