when one is adding an inline entity for a relation of a single card,
the 'add a new xxx' link disappears. If the user then cancel the addition,
we have to make this link appears back. This is done by giving add new link
id to removeInlineForm.
Schema of the data
------------------
First take a look at the data schema_ then try to remember that you are browsing
through a heap of data by applying stylesheets to the results of queries. This
site is not a content management system with items placed in folders. It is an
interface to a database which applies a view to retreived data.
