Snapshot 370 is now released

• Fix crash when opening render settings
• Press F1 in save search to open help text, which documents the new advanced search
• Expose sim.canMove constants
• Fix find mode always reporting 0 particles found
• Implement Lua tools, the new API will be documented soon

It's been a while since I posted about the last snapshot, but we've had 6 since March, they are definitely still a thing.

I'd also like to shoutout Snapshot 369, which renders the sim in another thread in most circumstances. If enabled, this can give a big performance boost on saves with lots of particles, and also lets you use Fancy mode without much performance impact.
