- Fixed a bug where the GUI would crash when filtering files that exist in a single sub-folder only
- Optimized some code
- Changed MO2 setting (if user uses MO2) to be saved and restored (mostly used for new skin installer function at this time)
- Added target path selector for skin installer, which lets users select mod folders (for non-mod-organizer-users the "game installation path" is the only option)
- Changed skin installer to now use this path instead of straight game installation path, which required changing from `OHSpath.CopyToGame` to straight `FileInfo.CopyTo`
