Completely rewritten dir tree generator
Previous dir tree was working via the usual recursive method of scandir The code was problematic as it was creating 3 dir trees and had an incorrect UL structure This now works in a completely different way, using PHPs inbuilt iterators Performance results are visibly noticable as file manager loads much quicker Tests show around a 100% increase in efficiency on servers with 1000's of files & folders There is also much less code, less repitition and it's much cleaner to work with The incorrect UL & LI structure has now been fixed and is valid Loads of junk and redundant code removed also
