GUI fails to launch when the secret key is unaccessible

[chrislee35]

In relation to issue #2, Hideio discovered a GUI launch bug when the secret keys are not found:
selectedKeyIds = new GPGKeyList();
for(GPGKeyId kid : secretKeyList.getKeyIDArray()) <-- crashes here
selectedKeyIds.addKeyId(kid);

I could hide the bug with some exceptions and default values, but I probably should present a warning dialog that no secret keys were found. The tool doesn't need secret keys to encrypt the email, but rather as a way of selecting the public keys that are most likely to be used. Furthermore, it decreases the chance that someone will encrypt to a key that they can't decrypt from.

So, a "fix" would be easy, but the proper interface will take time to think through... I think I'll patch around the issue for a patch-version, and then add the proper interface for a point-version later.

When I remove all keys, I get the following exception:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at org.dhs.chrislee.imapgui.KeySelectorPanel.addGPGKeyIDToModel(KeySelectorPanel.java:158)

I was able to do the first-level patch to this. Look for the changes in version 2.0.3.

Command line works but Gui not.
