V8.21.0

Features

• #576: /le stats area now shows the name of the player who holds each record (best time, fewest steps, fewest actions, most bonus).
• #577: Concentrators can now be selected as solidifier targets — when a solidifier targets an active concentrator, the laser the concentrator emits lays down colored glass just like a solidified laser sender does.

Fixes

• #578: Two lasers crossing on a solidifier now keep the first laser's glass color and filter the second laser instead of blending into a merged color; simultaneous arrivals still fuse as before.
• #580: Interactions with levers, buttons, doors, trapdoors, fence gates, chests, pressure plates and tripwires inside a puzzle area are now counted in the area action statistics.
• #581: A laser hitting the diagonal corner between two mirror blocks now always bounces back in every direction, and a laser striking the seam between two adjacent mirror blocks always reflects off the combined wall instead of disappearing.
