refactoring share templates to remove duplicates (rebased onto dev_5_0)

[atarkowska]

This is the same as gh-3124 but rebased onto dev_5_0.

This PR remove all data manager templates used in Public tab.

To test use users: share1 and share2 (make sure they do not belong to the same group):

---

• Log in as share1
• Select images add to basket
• Create a share with at least one user (user MUST NOT belong to the group where that image was imported): In the central window, click on the basket icon, choose Manage basket, choose images to share and use the Globe icon to create a share.
• Go to Public tab (left-hand Panel). Select the share. Check that the number of images in the share is correct i.e. Share Count
• Check than images in the share can be viewed using the Preview. Double click on the image and open the Full viewer
• Check also if you can browse through the data in Data tab (if you don't see anything different or any shares in the tree and if center panel works ok, including double clicking on thumbnails)
• Check if you can comment on share

• Log in as share2
• Go to Public tab (left-hand Panel). Select the share. Check that the number of images in the share is correct i.e. Share Count
• Check than images in the share can be viewed using the Preview. Double click on the image and open the Full viewer
• Check also if you can browse through the data in Data tab (if you don't see anything different or any shares in the tree and if center panel works ok, including double clicking on thumbnails)
• Check if you can comment on share

Double-click on the image does not work, only Launch full viewer.

[jburel]

The display of the members of the share should definitely be improved. see screenshot or log in as user-3 Share 21958 cc @gusferguson. This does not have to be done on this PR.

[atarkowska]

@jburel you cannot copy rendering settings when you are in the share. This PR is not about fixing that. Share can be definitely improved in develop this is rebase on 5.0

[jburel]

@aleksandra-tarkowska: as indicated previously some items can be covered in other PR since it is a rebase. The scenario also indicates "double-click". This is not working, error in scenario more that anything
Do yo have a ticket where I can add the various comments so it does not get forgotten?

[jburel]

clarification: I was double-clicking on preview item. Got mislead by scenario. I will add comment to the following card https://trello.com/c/9LEqQ1V3/82-share-general-comments

Merging.
