v0.2.0

• Feature: map and scenario editor (main menu Editor): new/open/save .MP2 maps, height, paint, fill, trees, territories, add buildings/industries/cities/rivers/roads, bulldozer, undo, Map Options and a scenario rules editor with live condition validation
• RE: editor tool routines ported from the executable (elevation brushes 0x426480, trees 0x429fc0, fill 0x490490, mixed paint 0x48cc00, rivers 0x429ea0, places 0x42f630, territories 0x4c8470) and the saver's map overview 0x477040, byte-identical to the original's .MP2 files
• Docs: editor screens L1..L13 and the editor chapter of the UI notes
• RE: Rare events in the fidelity scoreboard: prepared saves (re/scripts/wine/prepare_rare.py, rt2-savepatch) for train crashes, thefts and arrests, the board firing an AI chairman, creditor liquidation, AI stock trading and the AI's on-track engine swap; all identical to the original.
• Fix: Train crashes (0x4ce730), thefts (0x4ceaa0) with the nearest-town factor, arrests and the yearly theft-rate recovery now follow the original; a crashed train is removed when its wreck time ends.
• Fix: The annual review now fires the chairman and liquidates bankrupt companies (0x438170), and computer persons trade stocks (0x4a8af0).
• Fix: The AI's engine replacement on a train on the track (0x4d4e90) and the cargo lot of a removed car (0x4d0fa0).
• Fix: Town growth reads the live building count and a demolished building's list links are cleared (diverged with other RNG seeds at the year end).
