Android Changes

These changes resolve issue #177 and also add some missing files to the simple app solution.  Note:  Without these changes Csla.Android will no longer compile due to some additions to Csla.Core made to implement the Csla.Validation assembly.

Additionally I was originally forked from Rocky's fork instead of the MarimerLLC fork.  I changed that but that created a "merge" check-in.  I'm assuming that this is OK as the 22 files that changed all look like android files and are thus legit, but please verify before pulling in my changes.  I don't want to be the cause of any badness... :)

Thanks,
