[arch-dev-public] DB Scripts

Because of goofy errors and all that stuff, I moved new db scripts live. You will get a warning about "old add/del" directories until I (or someone) pushes out a new devtools release. I removed the need to the add and del directories in staging dirs, because db-remove is better at removing packages. The new scripts will not remove packages anymore when running db-update. Anyone interested in tagging/releasing a new devtools? Any additional devtools changes you want to sneak in there? Cheers, Aaron
