Simplify project format and prepare for 64-bit
This commit...
- Migrates to the new simpler project format.
- Changes the build target to 'Any CPU', so the mod is compatible with the upcoming 64-bit SMAPI.
- Removes the custom build script. The script mainly removed SVG/XCF files (which is now done with the mod build package), and renamed files starting with
[
(which didn't seem to do anything when compiled with Visual Studio or VS Code). - Updates the mod build package.
