This one is mostly tweaking the defensive buildings and polishing them up a bit, but there has been a change to how NPCs are saved that will break older saves again.

- Overhauled gauss cannons, they now shoot penetrating lasers instead of projectiles. Damage has been halved for balance

- Fixed missing collision at cave entrance after cave collapse

- Shattering platforms no longer visible before cave collapse

- Pausing now closes all other menus

- NPCs are now also saved by object name instead of index for future-proofing, forgot to add them in V0.6.0. This will once again break saves unfortunately

- Improved laser turret effects and added sound for laser

- Added visual indicator for when absorbing/venting energy

- Updated Arc Generator Mk. II sprites

- Fixed arc generator animation loop

- Improved arc generator AOE effects, added sounds, added slight screen shake

- Arc generators now knock back enemies and delay their attacks, but have significantly reduced damage output

- Removed erroneous description for gauss cannons saying they cost metal to shoot

- Improved drone laser effects and added sounds
