* Small correction for SHC_SAVAGE_IMPACT and SHC_DANCING_KNIFE skills
* SHC_SAVAGE_IMPACT should move the player from 1 cell to the target, between the target and the player
* SHC_DANCING_KNIFE shouldn't force the player to stand
* The behaviour should be the same for GC_CROSSIMPACT than SHC_SAVAGE_IMPACT
Thanks to @aleos89 @Lemongrass3110 !
Fixes#3310
