KDE 4.1.x schedule

[Albert Astals Cid]

We need to plan the 4.1.x schedule. There have been some translation team 
leaders asking me if it was worth translating stable branch as no 4.1.x 
release was annouced on 
http://techbase.kde.org/Schedules/KDE4/4.1_Release_Schedule

Tom Albers has suggested "getting the last tuesday of each month for the 
release and substract a week to find the tag date"

If everyone is OK with that i can update the wiki.
