Fix map versions

[DeadMG]

I initially rather liked FAF's built-in support for map versioning. Unfortunately, I've recently noticed that the system is, uh, less than fully implemented. The user cannot see the map version anywhere except by mousing over it in the lobby, so they can end up with three different Dual Gap EP Version 5s and no way to tell them apart when hosting the lobby or choosing the map. There's also the matter of the fact that users playing older versions of the map do not get updated, so the community fragments around the different versions of the map.

Recommend at least one of:

[*]Always update to the latest version when the user hosts on a map.
[*]Show patch version when choosing map.

my sweet summer child

also as the maintainer of gap ep maybe its good to say that version 5 is not an "official release"
im not even sure how it "nerfed strat rushes"
i would say stick to 4 but you're free to play whatever, have fun

As for a nice fix generally the thumbnails are generated on upload, maybe if it generated a version number on the thumb that would be cool, but i cannot see that feature being added anytime soon

If there was an active maintainer, I wouldn't have needed to do it myself ;p

I nerfed strat rushes by spacing out the mexes so that it's impossible to hit more than two with a single strat bomb, instead of all four.
