Subject: Session Management (restore on crash) This is HEAVILY based on code
from Lionel and Yoram branches. But this code behaves differently: it
restores rekonq tabs (just) on crash. Thanks to Lionel suggestions, it seems
"better" than my initial idea :)
It is quite extensible. We need just to fix it better as possible and then
manage its behaviour in newInstance code.. ;)
