* Finally remove debug-segment text, update Python imports to relative paths. * HUGE refactor to Regions/Rules to support move rando, first hub area coded. * More refactoring. * Another refactor - may squash. * Fix some Rules, reuse some code by returning key regions from build_regions. * More regions added. A couple of TODOs. * Fixed trade logic, added LPC regions. * Added Spider, Snowy, Boggy. Fixed Misty's orbs. * Fix circular import, assert orb counts per level, fix a few naming errors. * Citadel added, missing locs and connections fixed. First move rando seed generated. * Add Move Rando to Options class. * Fixed rules for prerequisite moves. * Implement client functionality for move rando, add blurbs to game info page. * Fix wrong address for cache checks. * Fix byte alignment of offsets, refactor read_memory for better code reuse. * Refactor memory offsets and add some unit tests. * Make green eco the filler item, also define a maximum ID. Fix Boggy tether locations.
