Move Configurations* out of the way and rename them.

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.
