hubertf 6c243d931c This patch improves the handling of save files in battlestar(6), by
allowing the user to choose the name of the save file and specify it
on the command line when restoring.  It also eliminates a buffer
overrun in determining the path to the save file, and any particular
arbitrary limit on the name length.  In the name of a tidier home
directory, the default name is changed from "Bstar" to ".Bstar".

Patch supplied in PR 8085 by Joseph Myers <jsm28@cam.ac.uk>
Minor modification (s/startup/filename/ in initialize()) by me.
