Get gdb working in AthAnalysis
This is a workaround to get gdb
to work in AthAnalysis
docker images.
I don't really understand why it's needed, and there are some issues with the debugging symbols being missing, but it allows us to attach a debugger and get a stack trace when something throws an exception. This is infinitely more useful than what we had before.
I also cleaned up the help formatting in a few classes.
