* 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

- Fixed the client range distance offset which is really 1.1 and not 1.0625
- This fixes the issue that when you sometimes tried to use a skill, nothing happened -> the client didn't make you move closer but the server said you are not in range yet
- I originally got an incorrect value through testing, because I didn't know that the client calculates range in a 3D room rather than in a 2D room, now I retested on a completely flat map; fully confirmed and official now

Fixes#3310
Replaced some still hardcoded values with their define constants.
Added a function to check if a walk will be diagonal and fixed invalid calculation for it.

* Alphabetically sorted includes.
* Updated copyright and license text to match across all files.
* Removed pragma once define in header files in lieu of ifdef guards.
* Initial progression of moving the map-server to C++ format.
