Allow custom rendering of inline images

Background

Inline images need a custom rendering in some templates. We want to provide this feature in the default template.

Requirements

• Implement INTEGRATED-889 Ready for client test
• File object should be passed to the template instead of the storage id (gregware needs an object and the file name is also needed)
• Classes must be passed to the template, because sometimes the view is changed based on classes
• Provide documentation for integratedfordevelopers.com about how to implement a template
• Provide documentation for integratedfordevelopers.com about how to implement a listener

Implementation requirements

• Allow customized rendering of images, but in the future also other inline items (video, objects, ins items, etc)
• Full customization need to be possible: resize the image to the required size, but a lightbox around it, etc.
• You need to be able to define the view in your template
• When no view is available the default template has to be used
• An example of the presentation need to be added in the default article view of the IntegratedWebsiteBundle:

Image rendering requirements for default template

• Max with of 1140px
• Max height of 600px
• class="img-responsive center-block"
• title = image description
• alt = image title
