Change to pyro flame movement.

Currently the pyros secondary ability is to switch between his IC and flamethrower. While good, it could be better and could improve his movement skills.

My proposal is two fold.

1. Change attack2 when you don't have the flamethrower equipped to switch to the flamethrower.

2. Change attack2 when you do have the flamethrower equipped to shoot flames behind you instead of in front of you. It could also be done from the back of the pyros air canister for fluff reasons.

I feel this alternative movement type would streamline the pyros movement set while giving him a unique secondary attack, something that I think most people want anyway.

It could be done so that attack2 drains ammunition faster or even does slight health damage. I feel this would help streamline the pyro in to an offensive fighting class without fundamentally changing how the class behaves. I also feel this would retain his defensive capabilities, something that may or may not be desirable.
