Added a major refactoring to include Emulated interface.

Browse Source 
It works in combination with virtualsmarcard module (vpcd). It properly installed, it creates a virtual reader that can be interfaced via PCSC+vcpd. At user app level, it has no difference of having a physical smart card.

At this moment, it only works emulating a CCID interface.
