Let the annotation indexer ignore .jar files that have gone AWOL

This happens for example when the ImageJ2 updater removes obsolete
versions, therefore we have to handle that situation gracefully.

Change the default log level to WARN

Several people have told me that SciJava applications currently produce
too much logging by default, and I agree. In particular, PTServices tend
to emit the number of plugins of various types that were discovered. I
think this sort of information _does_ make sense at the "INFO" level,
and that the default level should rather be WARN instead.
Avoid package-local access

It was clearly intended to be private.

WelcomeService: Show a specific welcome message only once

We should avoid pestering users with the same message over and over again.
Better to show it once, remember the SHA-1 checksum of the displayed
message, and then only show the welcome message again when the application
version number *and* the welcome message changes.
