create a "headless" agent for unix/linux

A no-gui lab128 agent that runs on unix/linux, that we could connect to from the lab128 client tool.
It would generate and store the lab128 .dt files for any locally configured db connections, which would be remotely accessible from the client tool.
This would allow for 24x7 monitoring of systems, and the ability to find the source of performance issues that had occurred in the past.
