Add new label (fixes #2501)

[paulbert]

Allows adding new labels from the dialog in the resource page.

Please test to make sure you can create a label and assign it to resources.

Next TODOs:

• Adding a label which is a "sublabel" or attached to other labels doesn't do anything at this moment. Need to show this in the filter view.
• Tags on the resource list show the id for a split second before changing to the text. Need to find ways to improve this.
• A manager list view of labels where they can edit them after they have been created.

Creating new tag is not adding it to resource immediately. It closes the dialog as well so user has to click again to add tag.
Also adding tag to resource is adding ID of tag as shown in image below

Add label is not selecting old tags so when submitted it removes old tags if not selected.

@lmmrssa

1. Yes that was another TODO that I forgot.
2. Could you send some more info about the resource which does not have its old tags selected? On my machine all tags remain selected when opening the dialog.

Regarding point 2. It seems like label is added but it was the issue of checkbox not being selected that when you select and unselect checkbox it removes label and you wouldn't know have you removed any previous label or not as all previous label were not already checked.

Label already added

Add label popup without old label checked

Checking new label confusing as its not clear which labels are there in resource right now

[lmmrssa]

Label auto selection is working now

not sure if it is only related to this branch or not but updated resource (video) does not load. Download of it works also it works with images. It works on master branch

@lmmrssa I don't think the video not showing is related as videos work locally for me. We can discuss at the meeting later.
