Dwarves, using aasimar template

I used the aasimar template and plugged in dwarf stats. In looking at
other SRDs races don't have descriptions, and I think I remember the
license doesn't extend to things like that, so if our OGL races are to
have descriptions, we need to write it.
Elf & Gnome, using aasimar template

As with dwarves, no description. The SLAs of the gnome could be better
formatted.
