Pronoun Substitutions

The following are used in omessages (ofail, odrop, osuccess, etc.) and the muf primitive pronoun_sub:

%a/%A for absolute possessive (his/hers/its, His/Hers/Its)
%s/%S for subjective pronouns (he/she/it, He/She/It)
%o/%O for objective pronouns (him/her/it, Him/Her/It)
%p/%P for possessive pronouns (his/her/its, His/Her/Its)
%r/%R for reflexive pronouns (himself/herself/itself,Himself/Herself/Itself)
%n/%N for the player's name

if it comes across a %x substitution, where X is any character not listed in the above substitutions table, it will search down the environment tree to try to find the appropriate %x property for use in substitution.
