Make it possible to use spreadsheet with Nuxeo Web UI

Nuxeo Spreadsheet is becoming the main UI for bulk editing data. From a given data table that lists documents, (button should also be accesible if it is the grid that is selecte), it should be possible to open the spreadsheet plugin in a separate tab, with the same page provider in the same "state". By default the spreadsheet displays standad colmns. The spreadsheet allows the user to select additional fields, that are displayed with a default mapping rule that leverages the references definitions (string ==>input text, date ==> calendar, vocabulary ==> suggest, ...)
