Add tags to display

[LavMatt]

This PR does a couple of things:

1. It changes the tag used in all search filters from display_in_catalogue to dc_display_in_catalogue
2. It implements a new property, tags_to_display, in the search_types.SearchResults class. This is populated in a post init and makes a list useing the tags property but excludes any tag with the prefix dc_.

Looks good.. my only question is do we need to separate out tags and tags_to_display? Or can we just replace the existing tags with the filtered list?

I thought worth keeping both as we may want to have other dc_ prefixed tags we don't display to users available to use to implement some logic
