Configure would load the glob "Configurations*".  The problem with
this is that it also loads all kinds of backups of those
configurations that some editors do, like emacs' classic
'Configurations~'.  The solution is to give them an extension, such as
'.conf', and make sure to end the glob with that.

Also, because 'Configurations.conf' makes for a silly name, and
because a possibly large number of configurations will become clutter,
move them to a subdirectory 'Configurations/', and rename them to
something more expressive, as well as something that sets up some form
of sorting order.  Thus:

    Configurations	->	Configurations/10-main.conf
    Configurations.team	->	Configurations/90-team.conf

Finally, make sure that Configure sorts the list of files that 'glob'
produces, and adapt Makefile.org.

Move the build configuration table into separate files.  The Configurations
file is standard configs, and Configurations.team is for openssl-team
members.  Any other file, Configurations*, found in the same directory
as the Configure script, is loaded.

To add another file, use --config=FILE flags (which should probably be
an absolute path).
