Batch annotation

Closes #762 (closed)

• A wild store module appears, annotation, which should handle everything related to the InteractiveImage.
  • display/imageEdit, display/editionMode, elements/defaultCorpusTypes, elements/selectedElement, elements/visible, elements/hovered are moved there
  • The annotation/create action handles creating an element with an optional classification
    • Batch mode is handled in that action with the least possible work done in the components
    • Classification handling is removed from elements/create
• While the store now supports a default classification, the annotation panel cannot yet due to issues with the MLClassSelect that will be done in a follow-up #885
• A missing unit test was added for elements/create error handling.
