I'm salvaging the changes to AccountManager and CharacterManager that
don't break the build too badly. This won't build, but it'll be easier to
rectify.
Also, I've reduced the length of the manager's method names, and renamed
sql_utility.*pp to sql_tools.*pp
This will allow the to be reused elsewhere, as well as cleaning up big
blocks of code in the manager's source.
BUGFIX: The config's key-value pair overrides now work without requiring a
config file specification.
