gdal.OpenEx() ignores gdal.UseExceptions()

[cdestigter]

gdal.OpenEx('bogus.filename') doesn't trigger an exception, even if gdal.GetUseExceptions() == 1

With gdal.OpenEx() verbose errors have to be explicitly asked with gdal.OpenEx(filename, gdal.OF_VERBOSE_ERROR), and when UseExceptions() is set, this will cause the exception to be triggered.

I've a local patch that if GetUseExceptions() is set will also set gdal.OF_VERBOSE_ERROR, so that an exception is automatically thrown, but I'm somewhat ambivalent about it. Opinions welcome.

Thanks, I'll add that flag.

IMHO making UseExceptions() set OF_VERBOSE_ERROR would be ideal :)
