- Adjust some consts so whip and firepunch work perfectly - Temporarily make AI draw expected traceshove trajectory while I'm working on baseball bat

Changed color of the "Natives" team to make it more visible and reduced difficulty of the "easy" challenge in the first mission.

Ignore all objects for fall tracing with shove to avoid considering checkins as obstacles. many objects will get knocked by the kick anyway, so end result should be pretty good. Oh, and ditch the sniper rifle doubling.

Fixed a bug where, after finishing a campaign mission, the user needed to reselect the team in the frontend in order to see the next mission.

Double sniper rifle damage (AI seems unaware of second shot, when playing). Spread out flakes along X when looping and add a little Y variation. This avoids noticeable patterns. Especially on the rarer close layer or dense flakes like rain (for Y)

Added the helper script I forgot to add last time

- Fix damage calculation in TestSniperRifle, aim a bit lower to compensate initial angle shift in sniper rifle. As a result, AI seems to never fail sniper rifle shots. - Temporarily make AI tell its expectations in chat

Copied the first two campaign missions and the helper script into share/hedgewars/Data/
