reddav vs. attach
Fixed some bugs with timestamps and timestamps for parent's folder on changes.

There was also a bug in SQL query of RedFile::put() that should have prevented this to work. Have there been problems on updating files? Could not validate it.

Bit confused about what's the difference between include/reddav.php and include/attach.php. What should be done in reddav and what in attach?
