Rewrites a lot of the config command to only do the minimum necessary steps to load the changes

Adds a ConfigTag class for helping to decide the action necessary for updating a given config option
Splits the color setting in PortalSignDrawer as only one color is set at a time when the /config command is used
Updates the configOptions map when a config option is changed
