Fix up all the mini-map stuff!

- Preset animated graphics now start at 960 instead of 400, due to all the new preset terrains from the previous commit running into their range.
- Tore out some optimization in the automap drawing, because it made it harder to figure out why it wasn't working
- Both game and editor now use the larger 12x12 map graphics, and fall back to shrinking down the 28x36 terrain graphic if no map graphic is set
- Upon loading an old scenario, map graphic is automatically set the same as the main graphic if it's a preset graphic; for custom graphics it's set to none
- Scenario now has three zoom levels for mini-map - the original in which the entire town is visible, a slightly closer one that matches the in-game view, and a large one using the 12x12 map graphics at full size.
- Fix some map patterns having the wrong bounding rect
- Graphics (and sounds) now included in the project by folder reference, so that I don't need to manually every new sheet to the project
