Overhaul player rank system

[aefreedman]

It's completely cosmetic right now, which is not a problem. However, it's also very boring and opaque.

Options:

• Add more ranks
• Use a non-linear curve to determine points-to-next-rank
• Make the level values and means of leveling up transparent
• Tie secondary cosmetic options to player rank (#38)
• Couple player rank to gameplay mechanics
• Give the player freebies for having high ranks
• Add a ladder and make it a side-competition
• Modify mission rewards via player rank
• Modify AAF or FIA capability by player rank

Caveats:

• Any alteration to the Rank system that affects the gameplay systems (i.e. if rank becomes mechanically significant) should be implemented carefully and will have secondary effects that may not be obvious until hours into a game.

Highest rank is supposed to become commander, but that's not a huge deal. If rank is tied to score they should probably be commander anyway.

FWIW I'm "for" that change ASAP and it would be real easy.
