Changed default colors of identifiers and metadata to irongui-default colors
Added switch to config for multi-lined Identifier information; text is now center-aligned
Added comments on supported identifier types and specific syntax to default configuration for dataservice
Changed default fallback values for identifier and metadata colors
Colors of identifier types can be changed independently
Removed tooltip for identifier/metadata information, instead added additional subscreen; adjusted splitpane behaviour
