chore: typo
feat: ThumbView also passes meta data to template rendering
refactor: responsiveAdapter is a singleton
refactor: ImageModel#getLarge and ImageModel#getThumb return responsive adapted preset data

BREAKING CHANGE: thumb-template gets ImageModel to work with

to migrate:
``<%= digest %>`` becomes ``<%= img.get('digest') %>``
``<%= src %>`` becomes ``<%= img.getThumb().src %>``
feat: ImageModel comes with filenameOrig attribute
feat: Cockpit body has it's own template and is therefore freely customizable by the lib user
