This hotfix fixes a handful of issues with the new Build & Battle PvP mode.

• Bugfix: Crash when modifying a ship's missile launchers in some very specific circumstances if the player has some but not all of the launcher munition technologies.
• Bugfix: It was possible to crash the game in Build & Battle by opening up a "Load Ship" or "Load Paint Scheme" dialog box from the paint, crew, or resource editors and then waiting for the battle phase to begin before clicking okay.
• Bugfix: In Build & Battle, exiting build mode before building any parts and then deselecting your ship could make it impossible* to re-select it to continue building. (*Technically you could still press Ctrl+A to reselect it, but this was not well-known.)
• Bugfix: In Build & Battle, if a ship is built without a control room, it wouldn't get teleported to the battle area and then would end up as junk in the build area that could get stuck inside the players' ships in future build phases.
• Bugfix: In Build & Battle, when a ship spawned into the battle area, it could get stuck on any junk that was left behind from a previous battle phase. Any junk within the ship's spawn area will now be deleted.
• Bugfix: In Build & Battle, it was possible for the READY and CANCEL READY buttons to get desynced from the players actual ready state, making it impossible to ready or unready.
• Bugfix: It was unintentionally impossible to build 1x3 Armor Wedges in Build & Battle.
• Ships in Build & Battle are now called "Unnamed Ship" by default.
