#97 Context Diagram supports selectable default person sprites

[kirchsth]

The macros are implemented based on issue #97:

PERSON_SPRITE_NONE()
PERSON_SPRITE_ACTIVE()  is default
PERSON_SPRITE_C4()
PERSON_SPRITE_3D()

and based on that the user gets with following sccript (typically the user defines the default icon only once and the include is on top of the file)

PERSON_SPRITE_ACTIVE()
Person(a, "user with default sprite")
Person_Ext(a2, "extern user with default sprite")

PERSON_SPRITE_C4()
Person(b, "user with C4 sprite no description")
Person_Ext(b2, "extern user with C4 sprite no description")

PERSON_SPRITE_3D()
Person(c, "user", "default 3D")
Person_Ext(c2, "extern user", "default 3D")

PERSON_SPRITE_NONE()
Person(d, "C user", "default NONE")
Person_Ext(d2, "extern user", "default NONE")

!define osaPuml https://raw.githubusercontent.com/Crashedmind/PlantUML-opensecurityarchitecture2-icons/master
!include osaPuml/Common.puml
!include osaPuml/User/all.puml

Person(cus, "user", "Custom", "osa_user_green_architect")
Person_Ext(cus2, "extern user", "Custom", "osa_user_green_architect")

something like

Hi, I updated and finished my PR.

These are my changes:

• add 2 macros
  HIDE_PERSON_SPRITE()
  SHOW_PERSON_SPRITE(?sprite)

• add 1 person (to the already existing one)
  person2 ()

@adrianvlupu, @Crashedmind: I didn't add the "3D" person, but I leave person2 (I found no lib which contains a similar sprite, and it has no [explicit] C4 relation anymore)

Best regards

Thanks for all your pull requests. I hope someone else takes the time to review them so that we can merge them.

I merged your pull request with my local branch and nothing seems to break.

• HIDE_PERSON_SPRITE() I fully agree with it
• SHOW_PERSON_SPRITE() I think should be named SET_PERSON_SPRITE() but it's not really a big deal

After merging, the methods should also be added to the C4.code-snippets file but I can do that afterwards, wanted to mention it so I don't forget.
