Fix 1920778: mons_open_door() not respecting gates

Also fixed several cases where secret doors would be described as rock
walls regardless of their actual type, and gates are now described
correctly as well. This means that viewing them also prints, e.g. 
"An open gate." or "A closed large door." without further information 
since there are no database entries for these specific cases. (Not the 
entries for simple doors are any more exhaustive.)

Fix 1910729: Yredelmnul's Drain Life not waking monsters, using 
             ncampion's solution.

Also default greedy_explore to true. (FR 1911112)
