Bring the wiki up to date with v1.6.0 and v1.7.0 Covers the over-full container warnings and Repair, origin tags, the identical-items setting, moving part of a stack and the theme-safe colours (issue #64), and records game 2.103 as checked with no save-format change.
Add the PCEdit wiki Two lanes off the Home page: a user lane (install, save locations, quick start, one page per editor feature, languages, FAQ/troubleshooting) and a development lane (architecture, the save-file format and library, app core, desktop UI, localization, item catalog, testing, packaging, contributing, releasing, supporting a new game version). _Sidebar.md carries the same structure into every page.
