Annotation Tool

Added Annotation Tool that allows you create annotation types and their occurences. It will also allow us to get rid of "Annotation" panel in N-panel.

I've recorded bunch of short videos to demonstrate the features:

- bulk tagging - currently works only for "Text" and "Stair arrow" type of annotations, adds annotations to all selected objects, automatically assigns products to the annotations

- creating annotation type with representation - all occurences will share the same representation which makes bulk tagging really powerful if you use variables like {{PredefinedType}}, {{GlobalId}}, {{Name}}, {{Description}}, {{ObjectType}}, {{Tag}}

- creating annotation type without representation - it allows occurences to have unique text or line geometry but still share the same classes from inherited property set

Examples:
  creating text type without representation to create title case annotations

  creating type for oblique dimension annotations

- readjusting - if you created some annotations using bulk tagging but the products were changed / moved afterwards now you can select those annotations and "readjust" them according to new product's position / measurements

PS In this commit I've also moved all icons to 1 .blend file and added instructions how to regenerate them.
