Adjust thickness and styles of element and boundary borders

[kirchsth]

related to #315

All element and boundary specific tags support $borderStyle and $borderThickness arguments (like the relationships with $lineStyle and $lineThickness).

UpdateElementStyle(...,?borderStyle, ?borderThickness)
AddElementTag(...,?borderStyle, ?borderThickness)
UpdateBoundaryStyle(...,?borderStyle, ?borderThickness)
AddBoundaryTag(...,?borderStyle, ?borderThickness)

All element and boundary specific Add...Tag(...,?borderStyle, ?borderThickness)or Update...Style(...,?borderStyle, ?borderThickness) calls (like AddPersonTag() or UpdateEnterpriseBoundaryStyle()) are extended too.

Additional a new border style SolidLine() is supported and can be used as $lineStyle= SolidLine() or $borderStyle=SolidLine() (like the already existing DashedLine(), DottedLine() and BoldLine() styles). It enables a reset of dashed boundaries).

' reset dashed back to solid (and set red border color) for all admin 
AddPersonTag("admin", $borderStyle=SolidLine(), $borderColor="red")

' set the (default) boundary thisckness to 3 (and use it for all persons) 
UpdateBoundaryStyle($borderThickness=3)

' system boundaries should use solid styles

Boundary(B, "All involved persons", $tags="persons") {
  Person(P,"person")

AddRelTag("admin call", $lineStyle=DashedLine(), $lineThickness=2, $textColor="red", $lineColor="red")
Rel(P,C,"uses")
Rel(ADMIN,ADMIN_C,"uses",$tags="admin call")
