Rank-based outposts

Introduce OutpostRank[RANK_NB] which contains a bonus according to
the rank of the outpost. We use it for the primary Outpost bonus.
The values are based on the trends of the SPSA tuning run with some
manual tweaks.

LLR: 2.96 (-2.94,2.94) [-1.50,4.50]

----------------------------

The inspiration for this patch came from Stefan Geschwentner's attempt
of modifying BishopPawns into a rank-based penalty. Michael Stembera
suggested that maybe the S(0, 0) ranks (3rd, 7th and also maybe 8th)
can still be tuned. This would expand our definition of Outpost and
OutpostRanks would be removed altogether. Special thanks to Mark Tenzer
for all the help and excellent suggestions.
