Support stereotypes in context diagrams

[marcelstoer]

Contrary to component and container diagrams the context diagrams don't support a fourth parameter for systems and persons: https://github.com/RicardoNiepel/C4-PlantUML/blob/master/C4_Context.puml

As per http://static.codingthearchitecture.com/visualising-software-architecture.pdf systems and persons can have stereotypes (those [] beneath the label).

Context diagrams don't support technologies because the entities can either be a system or a person.
The equivalent of those [] beneath the label in the pdf are the plantuml stereotypes

@marcelstoer: I think my PR #107 should solve your requirements. You could check it via my local branch https://github.com/kirchsth/C4-PlantUML.
E.g.
Entities can be decorated with tags and explained via dynamic calculated legends, for example:

@startuml
!include https://raw.githubusercontent.com/kirchsth/C4-PlantUML/extended/C4_Container.puml

AddTagSupport("v1.0", $borderColor="#d73027")
AddTagSupport("v1.1", $fontColor="#d73027")

Person(user, "Customer", "People that need products")
Person(admin, "Administrator", "People that administrates the products via the new v1.1 components", $tags="v1.1")
Container(spa, "SPA", "angular", "The main interface that the customer interacts with via v1.0", $tags="v1.0")
Container(spaAdmin, "Admin SPA", "angular", "The administrator interface that the customer interacts with via new v1.1", $tags="v1.1")
Container(api, "API", "java", "Handles all business logic (incl. new v1.1 extensions)", $tags="v1.0+v1.1")
ContainerDb(db, "Database", "Microsoft SQL", "Holds product, order and invoice information")

Rel(user, spa, "Uses", "https")
Rel(spa, api, "Uses", "https")
Rel_R(api, db, "Reads/Writes")
Rel(admin, spaAdmin, "Uses", "https")
Rel(spaAdmin, api, "Uses", "https")
