feature request -- "showdb" diagnostic

[David Starks-Browning]

Greetings,

Given that EMBOSS database configurations can come from 4 locations:

 - A file emboss.default in the share/EMBOSS subdirectory of your installation
 - A file .embossrc in the directory specified by the EMBOSSRC environment variable
 - A file .embossrc in the users home directory
 - A file .embossrc in the current directory

I think it would be useful, for diagnostic purposes, for a command
like "showdb" to report on what configuration files were read.  For
example, "showdb -debug" could contain this information.

(Apologies if this has already been added, I only tried showdb in
EMBOSS-2.5.1.)

Thanks,
David
