* Use portable Python for map merge hooks, other tools (#55658) * Add .dmm merge driver (#55699) This is kind of a prototype. It only fully handles a few situations, and doesn't produce particularly easy-to-read conflict markers when it fails. I hope that it can be useful at least some of the time, can be improved over time, and that the lessons learned can influence a future interactive GUI conflict resolver (integrated into StrongDMM?). In the worst case, one can fall back to the tried and true "manually re-do one side's changes" strategy. **Automatic use**: In `tools/hooks/`, run `Install.bat` **Manual use**, for Git GUIs that don't run merge drivers: while a merge is in progress, in `tools/mapmerge2/`, double-click `Resolve Map Conflicts.bat` This PR also removes the error-prone "Prepare Maps.bat" / "mapmerge.bat" workflow. Those who aren't using the hooks should instead use `Run Before Committing.bat` before committing. First-time contributors who opened a PR without map merging can be advised to run `I Forgot To Map Merge.bat`. * Fix loose double-quot in tradership_faction.dmm Co-authored-by: Tad Hardesty <tad@platymuus.com>
