V2.7.0 preview 4: Railgunner animations (Patreon)

Here's one last build before the public release. I added a bunch of animations on Railgunner to make it more interesting to play and raised the scope resolution for more clarity. I also made some changes to effect overlays and fixed some bugs. Just like Bandit, I added a setting to edit the two-handed snap angle as well.

CHANGELOG:
- Added Railgunner animations.
- Raised the scope resolution.
- Added a new setting to edit Railgunner's two-handed grip snap angle.
- The shield generator, plasma shrimp and shaped glass overlay effects on the hands are now smaller and more transparent.
- Fixed a bug that made the melee swing threshold settings affect only one hand on Loader and Acrid on future runs after changing it.
- Fixed a bug that showed the old bugged scope overlay on the HUD when spectating Railgunner.

This is your last chance to give some feedback before the public release, so make it count and have fun!
