Fixed some entrances that require reset otherwise
Fixed TR lobbies that need to be bombed
Fixed animated tiles in lobbies
Fixed wallmaster+lamp problem
Fixed some key rules that caused item requirements to be ignored
Fixed Old Man cave to be properly one-way in the graph
Fixed some odd key logic issues
-Rewrite of step 3b for accuracy - verified acceptable speed
--Can now detect an impossible balance situation and restart
-Eliminated false negatives in step 4 (still need to rework false positives)
-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
--Greedy equation finder not longer used destination/entrance sectors of the wrong split dungeon
--Required connections don't overestimate benefits
--Introduced the concept of crystal switches and doors blocked by blue barriers to equations
New algorithm also obsoletes sweep_for_crystal_access
Set up door and entrance caches in advance
Replace CrystalBarrier with FastEnum for bitfield arithmetic
--PoD Vanilla Stairway
--Boss should not be allowed key
--Scale back on aggressive layouts
Merge of attic hint
Non-chest keys hints added for figuring out how to get rid of them
Better batching support for mass testing of seed generation.
Generation issues fixed:
--Filler now tests with the key in the proposed location to enable alternate key rules
--Key rule checker now only considers key locations that the parent sphere did not have - better key rules
