Fixed missing variable
Update hotbuild upgrade action for engymod

Closes #34, but exposes a bug:

It's possible to build supportfactories without having the required HQ,
although they will not be able to build higher tier units.

I've ductaped this now in this buildaction, but that's not really a guarantee.
Merge pull request #65 from FAForever/feature/hotbuild-upgrade-engymod

Update hotbuild upgrade action for engymod
Update readme for latest feature
Integrated NetLag into FAF

Setting net_Lag to slightly above the highest ping among the players in a
game. This will reduce command lag, especially for 1v1 games.

Refactored the code to use average ping instead of a snapshot. It's also
taking variable pings into account by adding a headroom of std-dev*2.5.

Logging (although reduced) is still activated, this should be turned off
when everything seem to be working as intended
