Added Speck as a playable merc (by anv)
o Speck can be hired by M.E.R.C
o From now on, as long as Speck is hired (or dead, or POW, or travelling), he won't be sitting on Speck Com nor sending you emails. However, is he's able to, he'll comment on current situation from battlefield: player owing money, Flo getting married, MERC merc dying, etc., so keeping him alive might be a good idea
o GameDir data revision >= 1701
