[PATCH] Filters (against 1.2.3)

[Emmanuel <e allaud wanadoo fr>]

	Hi all,
here are (I hope) the last patch that deals with filters save/load 
problems. The last patches had different problems leading to incoherent 
filters config sections.
So if you encounter problems with preceding patches, try this one, it 
should be a lot better, and tell me if it's not as better as I think ;)
Sorry if one of the bugs hit you.
Patches are uploaded on bugzilla #63459
Bye
