Added flag to $tw.utils.parseStringArray to allow non-unique entries (#2027)

Browse Source 
* Added flag to $tw.utils.parseStringArray to allow non-unique entries

With this change if you use $tw.utils.parseStringArray(list) you get identical behavior to before and enforces uniqueness in lists, but if you use $tw.utils.parseStringArray(list,true) it allows duplicate values in the list.

Because of how JavaScript handles overloaded functions this shouldn't have any affect on existing code that just passes one argument to the function.

* Update to hopefully remove merge conflicts
