-Minor key logic improvement
--Introduced reachable_switches
--Calculate total completion in equation resolution
--Prioritized one-way connections over neutral/neutral_profitable sectored but not over dead-ends
--Simplified finding good complex branching candidates - just re-used equations routine
--Valid multi choice for global polarity when fixing parity
--Added total dungeon charge as critieria when fixing parity
--Pinball used for navigation in skull 2, marked appropriately (particularly with Ice Cross in Skull 2)
--Equation resolution detects used benefits with unreached_doors benefits

Access to Murahdahla's Triforce requires ">" 20 triforce pieces by default. This leads to 21 pieces available in beatable only and it means a hard crash if on tries to set it to 30 out of 30, as has_beaten_game cannot find a 31st triforce piece to beat the game
New algorithm also obsoletes sweep_for_crystal_access
Set up door and entrance caches in advance
