Logging Infrastructure / Normalize Paths

- Added base logging infrastructure
- Create scan log during library/game scan in %ProgramData%\CreamInstaller\scan.log
- Normalize Steam library paths (libraryfolders.vdf) using Path.GetFullPath + ResolvePath to handle slashes, casing, and drive changes
- Diagnostics.ResolvePath: wrap GetFileSystemInfos in try/catch and guard against empty results to prevent IndexOutOfRangeException (May assist with issues on slow or intermittently accessible external drives)
