DO NOT MERGE YET. 

@jlantz, 

We talked about you creating a branch for the new quickaction metadata type, that would then be merged into all  of our branches before this pull request could get accepted. Right now when I try running the deployWithoutTest target against my dev org I get a message saying that it doesn't find the Address__c.Update_Address action. I image it's because it doesn't find it in the package.xml file, since it's there in the quickactions folder.

Also, fyi, I had to manually delete the "New Address" action from the Account object, and the "Update Address" action from the Address object before the uninstall target was able to run successfully against my dev org. Not sure why these two actions are a problem.
