Mega-commit to the rescue! Added Javadoc snapshot (admittedly old); show UI now fixed-layout; UI uses system selection colours for accents; now uses bapsserver password and can thus talk to show database relations; removed member relation dependencies until further notice; attempted to get application and applet launchers working but having issues with the latter; started working on a server communicating via a minimal implementation of HTTP 1.1 (standardisation required eventually).
