Mod-Specific Defines

Used for #ifdef #else #endif tags to mark added or modified functions.
Mod-Specific GUID

Needed because every mod must have a GUID different from the base one.
Can Cache Double-type from XML

Doubles can now be cached from XML (in addition to Int, Float, and
String). DatabaseUtility was always capable of caching Doubles, but
Firaxis omitted it for some reason. Implemented just in case we might
need it later.
Now with Binomial RNG

Now has a second random number generator whose output has a binomial
distribution (versus the first RNG's flat distribution). Very useful if
you want a large range, but wish to avoid extremes.
Has Binomial RNG, Minor Civ Ratio Functions

Three new functions: one calls the binomial RNG (if it's enabled), the
other calculates the ratio of minor civs to major civs, the third
compares said ratio to the "default" ratio of 2:1.
