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 Michael

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! g

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