This PR fixes some math errors in Overmap Ship math that were causing
ships to have entirely wrong acceleration when moving in any diagonal
direction. It was off by about 30% in the diagonal directions. This is
also an alternate PR to #21620 which doesn't require changing the repo
to Byond 516
I hate this so much more than the other PR, I really badly need Vectors
for doing what I do, and to do stuff like this PR so much better.
