Growth modifiers gamedir changes (#40)

* Replace bEvolution with fRegresses

An evolution value of 2 meant that they devolved, so only Moses and non-sober Larry regress

* Update growth modifiers for specific mercs

Since we can't (currently) force a merc to not grow, we'll just set their growth modifier to an extremely high (slow) value

Len: extremely slow
Spike: extremely slow
Henning: extremely slow
Pops: extremely slow
Wally: very slow (Marksmanship only)
Carp: slow
Leon: extremely slow
Sam: extremely slow

* Add default growth modifiers (0) to the rest of the mercs
