[PATCH] new filters patch (new GUI-->comment it please)

[Emmanuel <e allaud wanadoo fr>]

	Hi all,
the subjest says all : I have posted to bugzilla a new filters patch.
It differs from others almost only from GUI viewpoint : I have tried to 
simplify it a bit.
Please tell me which one you prefer.
Consider this version as being less tested than others, I put it now in 
order that I can have feedback on the new GUI so that users have a chance 
now to make their choice. Polishing will take place in the longer term.
I have also made the "simple" filters case insensitive.
Bugzilla bug : 63459
Bye
Manu
