Inplace import icon dev 5 0, 11970 (rebased onto develop)



This is the same as gh-2116 but rebased onto develop.

----

Insight: Added an icon indicating that an image is an in-place import http://trac.openmicroscopy.org.uk/ome/ticket/11970

To test:
- Select a regular imported image: The inplace-import-icon should not be shown in the metadata view
- Select an inplace imported image: The inplace-import-icon should be shown like it was proposed in the regarding google document ( https://docs.google.com/document/d/1ZqJD0oyVOl5pnZR6w97PrskWM5U2C6QrrxNnPTyH4rk )
