[FIX] web: binaryfile field in list views

Revert partially 255e8ca3d92e3a77d7c2a145677623518bc2f978

Removed widget 'download_link', as it was a sub-version of widget 'binary':
it did the exact same thing (representation of binary fields by means of a download link)
in a much better-looking way (download icon + filename as text of the download link,
instead of just a download link with text "Download").

Also, the values of binary fields might be already a human-readable binsize (e.g. 2.52 MBs),
instead of its plain textual string representation in base64:
The contextual parameter 'bin_size', when set to true, does not download the data of binary fields.
As a consequence, the server provides the sizes of the binary, instead of their value.
