Add double weapon mode to polearms

[Wethrinea]

Like the quarterstaff, most polearms can be "dualwielded" in the sense that both the sharp and blunt end can be used to attack. I therefor with to suggest, if possible, that a property like the "two handed" be added to weapons in the polearm category, so that they can benefit from dualwielding feats by using -dualwield command, or something like it.

I'm rejecting this as I believe we already have enough double weapons, and I do not wish to rebalance these for duel wield options.
