paranoid_confirmation [expanded user patch] (trunk only; 2 of 2)

[Short writeup; see 'cvs log' of flag.h or options.c for the long one.]

     This is a reworking of user contributed patch known as Paranoid_Quit.

     Add a new compound option, paranoid_confirmation, accepting a space
separated list of values "quit die attack pray Remove"; default is "pray".
paranoid:quit   - yes vs y for "really quit?" and "enter explore mode?"
paranoid:die    - yes vs y for "die?" in explore mode or wizard mode
paranoid:attack - yes vs y for "really attack <peacful monster>?"
paranoid:pray   - y to pray; supersedes prayconfirm boolean; on by default
paranoid:Remove - always issue an inventory prompt for 'R' an 'T', even
  when only one applicable item is currently worn.
