0.3.2004.04 Fleet generator tool and fixes

This minor update adds a handy fleet generator tool to the battle sandbox. It allows quickly adding randomly selected ships similar to the battle setup screen. The tool may get introduced to the fleet and battle editors later.

Minor changes and fixes since previous patch notes:

• Changed large plasma projectile damage modeling to allow them pass through multiple modules but not being able to fully destroy a module with a single hit.

• Made large plasma projectiles cause external explosion if they hit ship exterior armor. This is intended to spread some damage to adjacent armor segments as well and generally buff these projectiles against armor.

• Added a plasma destroyer ship design. It is a medium size ship with large plasma turrets and shields but very light armor.

• Improved / changed ship peak power use statistic to include charging of shields and weapons. This makes the stat more useful and the power ratio stat to generally be less than 1.

• Fixed ships sometimes not getting to launch all their missiles due to issues in the launching logic.

• Fixed being able to queue launching of more missiles than were actually available.

• Fixed fleet battle AI trying to regroup even if it only had one ship.

• Fixed damage overlay rendering for ships that have kinetic shields.

• Fixed a rare UI overlay initialization issue related to mouse position update to the UI.

• Fixed certain single shot particle effects never getting to spawn their particles.

• Fixed module disabled and destruction particle effects not spawning when last module of a ship got destroyed.

• Fixed module destruction particle effects for ships's last module getting applied a random high velocity.
