repel adjustment
 

in order to make spears (as well as polearms) a bit better, i'd like to propose the following adjustment to repel:
when the att/def roll is made on the repel attack, the repelling unit gets a bonus to its att equal to the difference between the weapon's lengths. so the more of a length advantage the repeller has, the better it is at repelling.
this would also make some thematic sense.

doncorazon did a little testing, but even with -ddddddd, the debug log didn't provide detailed information on the repel rolls with whcih we could assess the effects.
