Show warning/explanation when viewing a lazer score page in non-lazer mode

[cl8n]

this can be confusing imo. someone viewing the website without lazer mode might end up on a lazer score page (linked from somewhere else) and see what looks like an impossible score with too low score value or wrong acc, etc

so there should probably be a note or badge somewhere that says it was performed on lazer

[peppy]

I think it would probably be best to always show which version the score was set on (maybe including the build number?)
