Updated JSEC-105

[Jeremy Haile]

I updated JSEC-105 to match the latest description of the Realm  
changes we want to make.  What do you guys think I should put the "Fix  
Version" target as for these changes?
http://issues.jsecurity.org/browse/JSEC-105
Once we release 0.9.0, we are going to migrate to Apache's SVN.  What  
would the next release be?  0.9.1? 0.9.5?  Whatever it is, I think we  
should target this change for that release.
