core: strip drive letters from windows paths

Browse Source 
Qt on non-Windows chooses not to recognize Windows paths, so we translate them to a Unix-esque path

QString StripWindowsDriveLetter(QString s)
{
// HACK: On Windows, absolute paths are saved with a drive letter (e.g. "C:\video.mp4"). Below,
// we use Qt's relative path system to resolve when an entire project may be in a different
// folder, but the files are all in the same place relatively to the project. Unfortunately,
// Qt chooses not to understand paths from Windows on non-Windows platforms, which causes
// this to break when a project is moving from Windows to non-Windows. To resolve that, if
// we're on a non-Windows platform and we detect a Windows path (i.e. a path with a drive
// letter at the start), we strip it off. We also convert any back-slashes to forward-slashes
// because on Windows they are interchangeable and on non-Windows they are not.
