GWT: Implement Pattern/Matcher emulation using RegExp
The RegExp implementation is more complete than the Avian. Also JsonWriter does not need an emulation anymore.

Hated to do it, but I needed it. Creating arrays is more efficient and relatively common. Fixed up a few places in libgdx using JsonValue.
