ngList always joins array with ", ", not with user-defined separator

[tedjp]

The ngList directive always joins existing data with comma-space (,), regardless of the separator specified by the developer - even if it's not a regex.

It would be great if the array could be joined using the same separator as is used for tokenizing (String.prototype.split()).

If it's a regex, it would be nice to be able to provide a separator (perhaps after the final / in the regex?) to be used when joining existing data. This would be useful when splitting on a newline (ng-list="/\n/"), or when both comma and semi-colon are allowed as separators (ng-list="/[,;]/").
