[BUG] Jumper wall bounce bug [FIXED]

[WillLem]

Reported by Paiy on Discord.

Because Jumpers now bounce from walls rather than falling, it's possible for the following bug to arise:



This is due to the fact that the wall check is repeatedly returning true, so the lemming continues to turn around. The fix I've applied is that the Jumper now has a "bounce allowance" of 3. Once this allowance is reached, the next time the Jumper meets a wall they fall; so, the end result is that they are facing the opposite direction to the one they were facing initally:



This has been implemented in Commit 6200e4307. A hotfix will be released shortly.
