Add image gallery theme

Resolves #6

Description

There are a lot of extraneous comments that came along with overriding core dspace-angular components and modules. We will be attempting minimal changes to files copied for overriding to afford easier synchronization when merging from upstream.

Reimplements image gallery theme by customizing collection, community, and search result grid components. The community components required fetching the recent submissions for the community and all custom components required template modifications. The grid component has styles customized to match the image gallery theme.

Instructions for Reviewers

Configure dspace-angular to point to dev environment DSpace REST API with config.dev.yml such as:

rest:
  ssl: true
  host: api-dev.library.tamu.edu
  port: 443
  nameSpace: /dspace7

Switch theme matcher to use UUID in regex until handles are supported:

  - name: image-gallery
    extends: tamu
    regex: 'befb7166-392b-445b-b907-1f4363bb6dfb|ed211f67-86ad-41ff-9696-fe0e7e17e1cb|d61f515b-8153-4718-9b9d-1ce679c955a0|c431e202-fc5b-46c8-b188-00901e1e215a|7c2ac72f-fd7a-4f27-b701-eb6e0539a876|beea4d64-0ff6-4e58-9f7b-489e1d6c6f75|282ec515-7b66-4492-b4d0-ae66d76f516b|6d433be8-7a28-4dc7-a245-f8dfbb7a513c|282ec515-7b66-4492-b4d0-ae66d76f516b|a3923d8b-249c-4b7d-8459-0c83953f7d8f|7c61a02c-2176-4c5a-9dd8-919353159e91|a4116d8b-8135-4449-a1b0-3378d5c7ecad'
