[class^="icon-"] selector clashes with other font lib

[emileber]

Specifically, the following:

[class^="icon-"]:before, [class*=" icon-"]:before {
  // ...
}

clashes with Simple Line Icons as you both use icon- as a prefix.

To avoid a breaking change, I would suggest doing what the other libs do and explicitly name all the icons instead.

Something like this:

icon-cricket,
icon-bicycle,
icon-baseball,
icon-golf,
icon-skiing,
icon-soccer,
icon-swimming,
icon-tennis,
icon-theatre,
icon-football,
icon-basketball-1,
icon-pitch,
icon-badminton,
icon-rowing,
icon-rugby,
icon-archery,
icon-baking,
icon-dance,
icon-bouldering,
icon-canoe,
icon-shooting,
icon-climbing,
icon-bowl,
icon-cycling,
icon-volleyball,
icon-unichallenge,
icon-trampoline,
icon-tabletennis,
icon-squash,
icon-sail,
icon-run,
icon-pool,
icon-goal,
icon-lacrosse,
icon-martial,
icon-hockey,
icon-frisbee,
icon-handball,
icon-fencing,
icon-horse,
icon-netball,
icon-darts,
icon-fulltime,
icon-halftime,
icon-kickoff,
icon-debate,
icon-starttime,
icon-cheerleader,
icon-pokemon,
icon-computer,
icon-boxing,
icon-croquet,
icon-cinema
