Lands http://codereview.chromium.org/194014 for Oshima:

* enable MessageBoxView
convert wstring to string16 when necessary using WideToUTF16Hack, which is no-op on Windows.
* updated checkbox to get state update working
state handing is a bit hacky, esp. b/c gtk sends signal even when the state is changed via API.
If there is better way, please let me know.

BUG=none
TEST=none
