OOM errors in Javascript force game to close

Increases simulation script runtime to 32 MB to reduce OOM errors, refs #1436, #1966, #2035

I was able to reproduce the OOM errors in a 1v1 multiplayer match with 64-bit Ubuntu 12.04 client and Win 7 host. It occurred after some thousands of units had been created (not all at once, they fought and died). The Ubuntu client got the OOM error, but not the host.

I've bumped the sim runtime up to 32MB as a solution for A14, but I think we should also investigate why memory usage is increasing and how we can reduce it, or at least what the best limit is (maybe based on testing very long games on giant maps with 8 players).

And for what it's worth, the "salad bowl" cheat is very useful for testing large numbers of units without having to actually play the game for long :)

I'm going to resolve these as fixed, but if you get more JS OOM errors, please reopen or create a new ticket and describe the game setup so we can adjust the limit (AIs, num players, map and size, player OSes, etc.)

Increase simulation script runtime size again. Refs #1436, #1966 and #2035.
