fixes historical figure read, fortress name

- 100.000 was much too low for a vector limit for some of the larger
vectors like historical figures. updated the check to 500.000
- moved the fortress name check to be done each read. this way you don't
have to restart DT after an embark to see the fortress name in the
window title
- preliminary orientation stuff added to dwarf.cpp (unused)
