[TML] Expanding the turret selection.

[Grimmund]

Of note from the SRD:

"Fixed Mounting weapons cannot move, are limited to firing in one
direction (normally straight ahead), and are found mainly on fighters.
A fixed mounting costs half as much as a turret of the same type, so a
single fixed mounting costs 0.1 MCr., a double fixed mounting costs
0.25 MCr., and a triple fixed mounting costs 0.5 MCr."
