* Got scancore scanning the agents directory, and properly holding on startup until at least one database is available (instead of exiting), and holding on startup until the local system is configured.
* Created the skeleton of the first scan agent; scan-network.
* Fixed a bug in Storage->check_md5sums() where dynamically loaded modules, loaded after the initial md5sum calcs, would cause the calling daemon to exit (possibly on every invocation).
* Created the scancore.README that will eventually be the main scan agent guide / API document.
