Weapon sort filter

@karllindmark 

Voalá, we have weapon stats with sorting and filters
Not sold on that one as it adds little extra complexity to follow up. 
Current approach depends on DICE not changing JSON, this guaranty that stats that do not have time equipped will not show k/min. Secondly above statement says show kills per minute WHEN killPerMinute not null (I'm on tablet) AND kills greater than 0 AND timeEqippped greater than zero. Meaning any of above failing this will leave view empty, where in reality I can have scenario of being on tablet and weapon equipped time few seconds with no kills where K/MIN should be showed :octocat:
