Support for %lvl% in TerrainInitTextures + cleanup

cleanup:
* Removed CProfile::SetUserPath (unused)
* Removed CProfile::GetUserBasedPath (unused)
* Removed CProfile::CopyFileToTemp (i have no idea why it even existed)
* Removed CopyFileListToTemp (it did the same as CopyFileToTemp but for multiple files, wasn't even fully implemented)
