Added notion of targetVersion

[mpollmeier]

Hi Graham,

I forked and amended dbdeploy to have the notion of a target version. Depending on the current version and we either perform an upgrade or downgrade. Theirfore I slightly amended the Ant API. Please have a look and let me know your thoughts!

Best regards, greetings from Cardiff

Hi Michael,

Apologies for taking so long to look at this, I haven't had chance to focus on dbdeploy for far too long. But I'm looking again now :) Thanks for the pull request!

This looks like a great simplification to dbdeploy, removing a lot of the clumsiness around undo scripts and "last change to apply". From the looks of it we can no longer generate an undo file, which makes a lot of sense, but I'm going to ask on the user list whether anyone desperately needs this feature before I pull. targetVersion makes a lot more sense and does everything and more, but I'm always nervous of taking features away...

And greetings from Kings Cross!

Any reactions on the user list in the last couple of months? ;)
Would be nice to have this in the main line of dbdeploy...
