Player moves faster while strafing.

The player moves faster while strafing. There could also be a running mechanic as well.

I think a possible fix for this is to divide the xd and yd by 2 when moving diagonally, but I choose not to make a PR, because I do not know how to edit the code myself.

You should divide it by 1.2 or 1.45 if I remember correctly

[El-Virus]

No, actually we should divide it by 2 as we have 2 values, the player will run at 1.4 or 1.7 the walking speed.

Put on hold since #199 needs to be done first.
