A few minor optimizations:

* Optimize swapwords and consequently shufflewords (which is called by g_maplist_shuffle) a little bit
* Avoid setting filename when not needed in Map_Check (called many times when the map vote starts)
* Save a few normalize calls in findtrajectorywithleading (called when bots use weapons like mortar and electro that fire projectiles with gravity)

findtrajectorywithleading patch probably causes a hash change due to extremely small aim direction changes (always < 0.0005) that at some point change the course of the bot match
