Class LinkTargetActionsViewExtension

Extends the action view of the linkUI plugin for link target display. This includes:

• render toggle buttons in the action view of the linkUI to indicate the set target of a given link
• executing a button will result in setting the target of a given link

When clicking the "Open in Frame" button, an additional balloon with a text input opens and allows setting a custom target.

The buttons to be rendered can be set in the editor's configuration. The default configuration is defined in linktarget.config.DefaultTarget.
