Fixes #1894: BASE is unloading JAR files too often

Deprecating JarClassLoader.unload since forcing an unload will trigger the problem if not all references are updated at the same time. This can only be ensured by the extensions installation wizard so it should all be handled from there via the autoUnload parameter.

As a consequence, the possibility to manually unload plug-ins from the web gui has been removed.
