1. Reconstructed menu to threads, which allows launching apps simultaneously - should boost kiosk mode
2. Added a new feature to allow auto-expanding paths in environment variables by adding an extra | (i.e. setenv=USERPROFILE|this| will turn the relative folder this into an absolute folder) - to support environment variables that rely on absolute folders
3. Added support for symlink when backuppath is missing
4. Added all environment variables to the menu and as a command line parameter /listenv
5. Minor code improvements
