Field widgets now have a key 'context' that let them
extend the context of the dataPoint (e.g. list).
In particular, widgets on binary fields enforce the contextual
item {bin_size: True}, so that the server gives the size of the
binary field as its value, instead of its content.
This change on binary fields reduces network load when accessing
a view with binary fields.
