multiple clients, reorganized projects

You can now run mulitple RMI clients. At the same time, even. Multiple clients for the same user and multiple users. (And I did add 2 more synchronization locks, but they're small.)

Further, I've reorgaized the code into 4 jar files:

1. AwCommon--common to the server, the clients and even used by rmiregestry.
2. AwServer--the application server and database.
3. AwTextClient--the interactive text and script client.
4. AwSwingClient--the Swing client.

Looking good. Note that I've now dropped the direct clients.

Looks like a servlet client is next on the list. This will give us a web interface.
