Balance : set base price for B12 to 30 and for the M4 to 20. (#5698)

# About the pull request
1-set base price for B12 to 30 and for the M4 to 20.
2-Medic comtech and SL have a discount of 20% because they have extra
supplies to by that are dependent on their role.
3-I also remove the free M4 for the FTL.
4-change price for drop pouch from 15 to 10

If you think M4 base price is to low i can increase it to 25.

if you think discount is to high or low i can change it...

if you think removing M4 to FTL is to much i can give them a discount
for armors or just for the M4 lowering it to 16 instead of 20

# Explain why it's good for the game
1-base price for B12 was already 30 but i am lowering M4 cost because it
only give limited advantage
2-Medic comtech and SL had all some sort of discount for a bunch of
items so here i am just picking a discount that seem balance.
3-This is to avoid people choosing FTL for the extra free armor instead
of picking Rifleman.
4-I think it's to expensive for what it is and it's very niche use. and
because Spartan asked me.
