Trait `insteadof` should be able to accept a name list, but only accepts a single name

[TysonAndre]

Version: between 0.0.5 and master

Expected: Should parse without error (<?php class C{use T1,T2,T3{T1::foo insteadof T2,T3;}} is syntactically valid)

https://secure.php.net/manual/en/language.oop5.traits.php#language.oop5.traits.conflict

(If there are 3 methods with the same list, one needs to exclude two of them, so it has to be a name list)

Observed: There were parse errors, MissingToken and SkippedToken were seen.
