Clean up template files

Clean up the files in /templates.

Example:
photos_albumlinks.html.twig

Will now be:
photos_album_links.html.twig

If you have any issues with this, clear cache. Any custom template files will have to be renamed to match. Also check CSS classes if you have custom CSS, some classes are being renamed.

Tasks:

• Clean up template file names.
• Remove table layout from photos_image_block.html.twig.
