On the road to 0.3 series. Think about remove NAPI and be asynchronous.

Split plugin:
   - move native plugin to a chrome extension
   - provide asynchronous scardjs for user page (use Q-Promise)

Provide test page in dist.

Provide new doc as a generated JSdoc.

Some API are not yet supported:
  - SCard Start|End|Cancel Transaction
  - SCard Control
Will be readded in next push.

Note:
  Native plugin has not been refactored for now. But stop to use it directly, next push may overkill its API.
  Use scardjs.js lib.
