The lower two levels of Vlad's Tower were got showing the wizard-mode
special level indicator '[level_abbrev]' in #overview, nor appearing
for ^O or in the level teleport menu, indicating that Is_special()
wasn't finding them. It took a while to figure out why, but the fix
is trivial.
There is a lot of code affected by this, and Pat Rankin correctly
observes that it would be better to store roguelike as a level flag
rather than just using Is_rogue_level. A note for the future.
This patch adds several new levels from <Someone>'s Gnomish
Mines patch, after devteam revision.
The ordering of levels in mines.des has also been cleaned up.
