Standardized config settings

[Peter Tigges]

instead of this XP-MULTIPLIER=1.0

• CHARACTER-BUILDER=true
• CHARACTER-FIRST-ZONE-MESSAGE=
• CHARACTER-SPEED-HACK-CHECK=true
• CHARACTER-XP-MULTIPLIER=1.0

cfg settings should be grouped with feature being used first in the naming

We'll be using very long strings and moving them to a different config will require renaming of the string (thus having to edit the code). I think it's good as it is.

Additionally, the XP multiplier is global. It will also apply to beasts.
