djinni are now unsolid instead of poisonous
remove M2_STALK flag from riders
corpses are no longer defined as giving stone resistance

this was unimplemented, I am not sure whatever implementing this would be a good idea (rubber chicken is still overpowered, footrice would be trivial with this one, chromatic dragon scales are enough as stoning resistance goes)
allow even longer messages
show monster type info on farlook (inspired by Pinobot from #unnethack)

requires previous commit to work properly, requires modifications to monsters definitions to not show misleading info (monsters supposedly granting stoning resistance) (done in parent of the previous commit), the next commit removes debugging code. In addition it assumes than Riders' info is not obscured like it was done in UnNetHack (and rewerted by UnNetHackPlus) - direct applying this patch to UnNetHack would allow to reveal rider info on any distance, with a simple farlook (dragons' attack hiding is inplemented).
removal of debug code
Vlad is scared by altars, minor refactoring
Merge branch 'refs/heads/pinobot'
