hide downloaded traces by date/level of detail

[richlv]

in some areas older traces are either of really bad quality or just plain wrong after "on the ground" situation has changed. that makes them almost unusable sometimes, and, as the amount of traces increases, this becomes more important.

one example might be ​http://www.openstreetmap.org/?lat=56.9565&lon=24.2523&zoom=14 - lots of traces go over the old road, which is not passable anymore.

it would be nice to hide traces by :

a) their age (timespan in downloaded traces layer info)
b) timestamps being provided (allowing to hide traces that show no speed info)

b) might be included if a) is available :)

ticket #4133 asks for an ability to hide individual traces

[Polarbear-j]

this functionality is meanwhile provided by GPX filtering in core
(right-click GPX layer, select funnel icon)
