Mark problems as ignored

[GaurangTandon]

Sometimes certain problems are too easy, even in higher rated sections, and you want to ignore them. I can visualize a simple "mark as read" button next to every unsolved problem that if checked will give a yellow background/strikethrough (some visible feedback that the problem is ignored.)

Data can be stored in local storage.

Thoughts?
