add way for simulator to return select data

[klali]

changes some underlying dynamics but keeps the current api where selectApplet() returns boolean and adds selectAppletWithResult() returning byte[]

also fixes #21 by calling the process() method once with selectingApplet true.

I'm not sure this is the "correct" way of doing this, but seems to work fine enough for me, though completely open to opinions/changes/etc.

Any updates on this? If it's not acceptable in this form (or at all?) that'd be good to know..

Hi, We did not forget about your pull request. Prior to implementing Global Platform we were planned to rework the mechanism of interaction with applets, by adding CardManager entity, which receives APDU commands, implements security policies, works with SecureChannel and interacts with applets. Unfortunately, we had no time to implement it fast, that is why your pull request is stuck a bit.

We are ready to accept it, but there is one wish: replace Simulator method

 public boolean selectApplet(AID aid) throws SystemException {
          return SimulatorSystem.selectApplet(aid);
      }

on

 public boolean selectApplet(AID aid) throws SystemException {
       byte[] resp = runtime.selectApplet(aid);
        if(resp != null && resp.length > 1) {
            int len = resp.length;
        if(resp[len - 2] == (byte)0x90 && resp[len - 1] == 0) {
            return true;
            }
       }
       return false;
 }

and remove static boolean selectApplet(AID aid) method from SimulatorSystem

Thank you very much for your contribution in jCardSim project.

I've just pushed a new commit there which I think does what you suggested..

Very happy to contribute to jcardsim, it greatly simplifies our testsuites for applets.

It's great! Thank you very much for the commit!
