#287 System and person support [...] notation

[kirchsth]

close #287

C4 Model extension: Person() and System() support $type argument too.
Is uses the same notation as $techn, e.g. $type="characteristic A" is displayed as [characteristic A]

Following macros are extended with the optional argument $type:

• AddPersonTag(), AddExternalPersonTag(), AddSystemTag(), AddExternalSystemTag() is extended with $type as last argument.
• Person(), System(),... is extended with $type as last argument.
• cleanup of AddNodeTag() that it can use $type like in the Node() call itself.

@enduml

It can be tested with my extended branch

@mtnpke, @Potherca: $type enables the simplest merge, therefore I didn't change it, but if you want I still can change it in this PR
