Slight adjustments to world name generation. 2D6 OGL rules file now
useable as a standalone script with text output.
Modified world generation to seperate attribute code generation and
attribute description generation.
WARNING: Breaks old rules files.
Implemented a fix that falls back to the old world generation function if
the new ones aren't implemented in the rules file.
Fixed a bug in the 2D6_OGL rules script that capped world attributes
