New command "qstrcmp"

qstrcmp <quote1> <quote2> <var>

Compare two quotes. <var> returns zero if they are identical, -1 if the first quote comes first in alphabetical order, 1 if it comes later.

Note that the lexicographical order is rudimentary, for example "Player 2" is considered greater than "Player 10".

Patch from Fox.
