Extra copies of dictionary words in z3

[fredrikr]

If you compile a game to z3, and there are two dictionary words in the source code which are not different with the six-character resolution of z3, but would be different if the resolution was 9 characters as in z5, they are created as separate dictionary words, which causes all sorts of problems. Example:

Object Scorpion "scorpion"
with
name 'scorpionx' 'scorpiony';

This creates two dictionary words: 'scorpi' and 'scorpi' (truncated to six characters). Depending on the interpreter's method of searching the dictionary, one or the other may be matched when the player type a word beginning with scorpi.

I think the fix would be to add a version_number check to the line

if (i>=9) break;

...in dictionary_prepare_z()?
