Arrays comparison via '==' and '!='

Reports usages of == or != operator for arrays that should be replaced with contentEquals().

The == and !=operators compare array references instead of their content.

Examples:

fun test() { val a = arrayOf(1, 2, 3) val b = arrayOf(1, 2, 3) println(a == b) // references comparison }

After the quick-fix is applied:

fun test() { val a = arrayOf(1, 2, 3) val b = arrayOf(1, 2, 3) println(a.contentEquals(b)) }
