From Alan Harris, "Registry and Archive

Browse Source 
~~~~~~~~~~~~~~~~~~~~~~~~~
This is a simple change to permit databases other than those named
"*.osga" to be used. It is hardcoded in read() at present.

It is non-critical and does not affect existing program functionality.

Registry and Registry.cpp
~~~~~~~~~~~~~~~~~~~~~~~~~
Added a new typedef:      typedef std::vector< std::string>
ArchiveExtensionList;

a list of extensions:     ArchiveExtensionList  _archiveExtList;

and an "add" method:      addArchiveExtension(const std::string ext)

This is initialised by adding "osga" in Registry() and used in
Registry::read() where the list is searched for the extension used.

Archive.cpp
~~~~~~~~~~~
This submission is a little more tentative. openArchive() is modified to
automatically add the filename extension to the Registry extension list.
