Replace autocomplete fields by drop-down Fields

[p-a-s-c-a-l]

Please replace all autocomplete fields by drop-down fields / lists when selecting existing terms from a taxonomy to give the user a chance to view the selectable options. E.g. consider the following example: It is not possible to choose an existing license for a Data Package if you don't know the name of the license.

I replaced the inline entity form of the *spatial context/grid property by a select list, since we should reuse as much entities as possible. E.g. the spatial context (including its grid) is the same for the different HC Datasets I'm going to add. So there's no need to to duplicate all this information.

However, in the select list, it's not possible to add a new entity:

Is there something like a "select or create new" editor form?

For adding or creating and add a new entity to a reference field there are two possibilities:

• Inline entity Form of type complex. Here you can select if the user can create and/or select existing entity. But the selection widget is an autocomplete widget.
• Entity Browser. Same idea as Inline forms but a more flexible implementation. Entity browsers are managed at admin/config/content/entity_browser. If you want to offer a selection you have to create a view of display type entity browser first.

I replaced your select list by an entity browser for grids. For now it is an iframe, but we can make a modal popup as well

I created the remaining Entity Browsers for Contributors, Sources and Licences (which are used both in the forms for data package and dataset) in the same way @fgeyer16 did for the grids. Other than that I didn't find any other autocomplete fields which should get replaced.

Some CSS changes need to be further applied (should hopefully be done by the end of the day).

CSS changes were not necessary in the end, we just had to set the appropriate formatter for the Entity Browser display inside the forms.
