Final Fantasy III: Economizer MP tweak

The Economizer made all spells cost 1 MP, a feature that is about as game breaking as a game could possibly get, short of implementing a "win the game" button.

C3/510D - C3/51C5

Urgency: Low to none. This isn't a bug by any regards, just something I found
to be annoying and abusive. (Somehow I think I've heard that before.)

Description:

The Economizer made all spells cost 1 MP, a feature that is about as game
breaking as a game could possibly get, short of implementing a "win the game"
button.

--------------------------------------------------------------------------------

What this patch does:

Gold Hairpin - No direct tweak, MP cost is still reduced by 50%.

Economizer - Reduces MP cost by 75%.

Enforces a minimum cost of 1 MP for every spell, regardless if either relic was
used or not.

Changes the description of the Economizer to fit the new rule.

Version history:

v1.0b - April 25, 2010. Fixed problem with null entries in the menu. Every null
entry would have a 1 MP cost. To do this, the code determining the MP
cost and the following code for availability had to be optimized.

v1.0a - January 19, 2010. Fixed readme, it was incorrectly stating where the
code was going. Optimized code in both C2 and C3, no free space used in
either bank. Zero possibility of conflicts! Take that!

v1.0 - January 19, 2010. Patch conflicted with assassin's Alphabetical Rage
patch. Code was greatly optimized, and uses far less space than it did
previously.

v0.1 - March 29, 2006. This date is assumed. Preliminary version.
