ZeroK: Zero-K updates to Spring Engine 83!

From ZeroK: link to original post

At last, we are switching to the latest engine version which features many improvements (performance, visuals) and fixes (vehicle pathing).
Full changelog is here https://github.com/spring/spring/blob/master/doc/changelog.txt

ATTENTION:
TO UPDATE SMOOTHLY:

• on windows, restart Zero-K lobby 2x and join the game
• if on linux, wait for package update and follow links at http://springrts.com/

Note that this engine is a major update and it will certainly contain new bugs too. We will be addressing those asap.
Enjoy!
