French Winawer: Poisoned Pawn, Eingorn and Warsaw variations

[seccohazy]

In my attempt at a first pull request I added the "Eingorn" and "Warsaw" variations, and corrected the starting moves for "Poisoned Pawn".

The 7...cxd4 move order, if it is truly "Poisoned Pawn", will transpose into the "Main Line" or the "Paoli Variation". So I figure 7...Qc7 must be the earliest unique shortest line.

Corrected the order by names, should be good to go now.
