Better way to clear search filters

[johanfforsberg]

Right now the only way to remove the current search filters is to click the "clear" button in the search field which will remove all filters. This is kind of unintuitive and also not very fine grained. It would be nice to be able to e.g. click a filter at the top of the logbook display to remove it. Also, maybe the "clear" button should be moved there instead, in some form.
