Support PlantUML user preferences on the CIMTool Preferences dialog

[tviegut]

With the introduction of PlantUML diagram generation in 2.2.0 the ability to support end-user preferences on the CIMTool Preference dialog is desirable. This issue is for introducing the following configurable PlantUML preferences for the diagrams generated in CIMTool:

• Configurability of the color of concrete classes within diagrams (default preference should be #lightyellow)
• Configurability of the color of abstract classes within diagrams (default preference should be #lightgrey)
• Configurability of the color of enumeration classes within diagrams (default preference should be #lightgreen)
• Configurability of whether or not to display the cardinality (e.g. [1] or [0..1]) for required attributes in a class. Not showing the cardinality aligns with common UML class diagram conventions where cardinalities of 1 are not explicitly shown and when not shown are assumed as required. (default preference for this should be to display cardinality for required attributes)

The configured values for these preferences would, in turn, need to be passed along to the new PlantUML builders to use during generation of any diagrams.

Would it make sense to have this as an option? I just think that in the case of domain expert that shall read the UML model they might not know that the default is 1..1.

@Sveino : Thanks for the quick feedback. Ironically, I just finished adding end-user preference to change the default colors for concrete, abstract and enumerations in the CIMTool preferences screen. I just went ahead and added this also as a preferences setting based on your feedback:
