[gemini-dev] DBAccess refactoring

[Mike Keith <michael.keith@xxxxxxxxxx>]

Juergen,

I did what I had been meaning to do for the last few months -- refactor 
the DBAccess code base to make it more extensible for other DB 
platforms. I also checked in the support for MySQL. I haven't added the 
tests, yet, because that is going to involve doing some test refactoring 
as well. Not sure if you have any specific ideas about how you you would 
like the tests to be structured to cover different databases.

Anyway, feel free to reorg it again, but at least now it should be 
really easy to add support for new DB platforms.
