Fixed Day (was getting Month)

I applied this on cran/RISmed too; not sure where is the proper place!

Hey, Thanks for pointing out the day problem. Your correction has been incorporated into the current version.

I also did a fairly extensive revamp of the date variables to reflect more aspects of the publication history (accepted, received, ppublish, etc.) If you could install the package from the repo, and let me know what you think about the date methods (Year, Month, etc.) that would be great. One problem is that the different parts of the history are not always consistently populated so there are usually NAs in any particular history field.
