Added a new Island branch, based on dpeg's ideas.

In any given game, either the Islands or the Swamp will be generated (50%
chance of each) as Lair subbranches.
The Islands have a ranged-attackers theme and are 5 levels deep.
THIS IMPLEMENTATION IS INCOMPLETE, so beware! The following things need
to be added:
1. A level-5 vault to contain the islands rune (the rune is coded, but
it doesn't show up yet - so for now, if you get the Islands, you'll be
stuck with one less rune.) A unique Cyclops, Polyphemus, to guard it might
be a nice idea. Perhaps we should block controlled teleport until he's
dead, too.
2. Making the island structure depth-dependent (i.e., more islands on
deeper levels.)
3. Shallow water fractalisation.
4. Probably more stuff I forgot.

I also put in various minor fixes.

Breaks savefiles, possibly highscores too. I'll put in a savefile version
bump later.
