Wall climbing!

Someone suggested to me that the sniper wall climb mechanic from VSH and FF2 should get added to jump, so I went and did just that! As a sniper you can now melee the wall (with any melee weapon), and you can climb upwards.

Figured it'd be a fun thing to add, since we already have stuff like spy bungee which can already get you past difficult jumps.

I don't get how this is labeled Gross, but awesome! Now you can bushwacka jump in a place meant for jumping!
