Adapt previous/next buttons to the filtered search

Right now the next and prior record navigation buttons on an observation simply use the observation ID # to navigate.

It would be nice if they were more responsive after you have filtered or searched. For example if I have run a search and am viewing records of Painted Trillium in Ontario, when on a record, if I click the next button, it should go to the next Painted Trillium record in that datasets, not some random unrelated record.

Much better for viewing data, and adding annotations, observation fields etc.
