Added more Alastairs plus the 'Dates Added' row

To make it easier to see when the different Alastair's were added to the page, I decided to start marking them with the 'Date Added' row. I tried to go back in my memory (which isn't so great sometimes) and remember when I added the older Alastair's, but since I work on the page at random that was pretty hard to do.

Anyways - enjoy the updates!
