Add image annotations to the full report.

[dlangenk]

Whole image annotations are missing in the full report as requested by lenaick.

Wouldn't a separate report for image labels make more sense? I don't see how we can cram all this information in a single tabular report in a sensible way.

[dlangenk]

This would be fine as well.

I already see the next feature request coming, since they are probably labelling the images with the substrate_type label tree. They probably don't want to see this for each image:

- bedrock
- cobbles
- gravel

But this:

- substrate_type > dominant > bedrock
- substrate_type > secondary > cobbles
- substrate_type > tertiary > gravel

The image label report is now implemented as XLSX with one sheet per transect and the format:

transect_name
image.id	image.filename	label_1.name, label_2.name, label_3.name, ...

If this feature is urgently needed we can deploy it now. However, I'd prefer to wait for the Laravel 5.3 release (probably tomorrow) when we can finally merge #4 into master and then deploy both features by friday.

@dlangenk This feature is now live.
