Small bonus to favor thorn pawns
We increase a little bit the midgame value of pawns on a4, h4, a6 and h6.

 Original idea by Malcolm Campbell, who tried the version restricted to the pawns on the H column a couple of weeks ago and got a patch which almost passed LTC. The current pull request just adds the same idea for pawns on the A column.
Possible follow-ups: maybe tweak the a5/h5 pawn values, and/or add a malus
for very low king mobility in midgame?
