[FIX] web_editor, website: permit the user to set link on images

This restores a (basic) feature that was lost in 15.0 by mistake.

Allow the user to set a link on an image. The user can access this link
tool in the editor panel or via the CTRL+K shortcut. This tool is very
similar to the existing link tool for texts. This tool uses the
suggestion system already existing on the text link tool.
