Resuming use of GitHub

Re-committing the change backlog that has developed in the 5 months
since I last used GitHub.
Light flare for explosive bloat explosions; trapdoors won't count as chasms for purposes of lake boundary cleanups; fixed some broken DFs.
Potions of incineration are now light flares.
Collapsing floors now flag interiors

to avoid screwing up the stairs
Gem altars no longer require distinctness (since that caused a bright gray circle)
Monster-dropped items can't land on top of other items.
Ran analysis, implemented some changes including several possible bugfixes
