* Added create-folders command. Folders for sync will be created by this command and not with shell commands (mkdir....).
* Options --start-progress and --total-progress become optional (for commands that accept them). Not supplying means there will be no progress report.
* InstlMisc commands can report progress, some do it with staccato.
* InstlMisc commands report execution time.
* Windows: robocopy copy_dir_to_dir has /PUSRGE parameters so that redundant files in hte target will be removed.
