Multiple regressions after last PRs

[joseluis]

After all the PR merges some things have broken, several things have reverted, other need to be updated, and some other things were broken before and I just found them:

• Typo: Influnce → Influence
• Regression of assignment arrowhead
• Regression of access dotted line
• Regression of using unespecific technology-process/interaction/event icons, which now exist because they where added in Fixed some archimate icons plantuml/plantuml#205 last year
• Missing rounded corners for: business-event related Added business location #11
• Missing horizontal lines in spec to Business_Contrat, Business_Object & Business_Representation
• Bad icon for Technology_Node, Equipment_Facility, Physical_Facility after their conversion to node
• Remove unneeded horizontal lines according to spec, from Material, .... TODO
• Wrong Location color
