Update 509: Blinding Arrow

[h3]Fixes for invisible players/objects, 12 round ranked gamemode, ranked leaderboard.[/h3]

[h2]Gameplay changes[/h2]

Fixes to objects not getting cleaned up properly. This should hopefully reduce or resolve issues with players/objects "going invisible" on some clients.
Ranked is now a 12 round gamemode. New maps are selected after 6 rounds. Both teams will get a chance to start a set of new maps on the defending and attacking sides. For example, if you start attacking, you would play attack, defense, (new maps), defense, attack.
Added Best of 12 UI to the ranked gamemode. This includes a match timeline component for the map changes.
UAV view updated to show information about the match timeline
Additional safeguards to joining in progress, defenders shouldn't spawn outside or in the floor due to this.
Barbedwire hitboxes were fixed to prevent blocking bullets
Inputs are locked during level loading phases, this has a known issue of some weirdness with the camera at the end of rounds.
Fixed an error with client simulation
Fixed issue with factory wall charges stopping client simulation.
