BottomFeeder updates changing

I've changed the update mechanism for BottomFeeder. We were delivering patches automatically at startup. The next release (and current dev builds) don't do it that way. Instead, all components can be updated on the fly - just hit the update button on the Toolbar, and a list of appropriate updates will be shown. If you decide to upgrade, the update(s) will be downloaded and loaded into the running system.

This is also the way you select plugins for download now.
