[PATCH] fix #47996

[Michael Brade]

Hi!

Coolo said fix it, so the attached patch fixes #47996, please review. I added 
a method checkUpdate(dir) that checks if dir should be updated or delayed. 
slotFileDirty now delays all the update events it gets by 500ms (that's the 
STAT frequency) and drops all other events for the same file during this 
time. I don't know why FAM is flooding KDirLister that much but during this 
500ms delay I got 100 (!) FAM events. Phew. The only bad thing is that my 
patch adds another QDict (the timers) to KDirListerCache. Ok, it's not too 
much, but anyways, it's additional bloat because of FAM going mad :-/

Also, slotFileDirty was the only method that updated files and directories 
even if they were in itemsCached. Fixed.

Will commit tomorrow (damn, I hate to work at night... will be really tired 
tomorrow :( )

Ciao,
