Use of asset collections and tags is bound to read-only status of an asset source

[kdambekalns]

Description

Asset sources have a method isReadOnly() to tell whether they are read-only or not. A read-only asset source does not allow their content to be changed.

That read-only state is coupled to the display of asset collections and tags in the media browser, though. And that does block any asset source from using collections and tags to group items – something that might very well be possible based on data in the asset source.

It would thus be great to display asset sources and tags (minus the editing functions) even if an asset source is read-only.
