*bool instead of bool

[gasperinn]

I have a problem with setting ForegroundShow to false. Because of the omitempty tag in the definition the variable is not presented in the final json structure sent to the push api:

ForegroundShow bool json:"foreground_show,omitempty"

I suggest changing all bool values to bool pointer type *bool:

ForegroundShow *bool json:"foreground_show,omitempty"

It shoud work as expected:

• If you don't set the variable then it will not be presented in the final json structure
• You can set it to true like that:

foregroundShow := true
msg.Message.Android.Notification = &hms.AndroidNotification{
	ForegroundShow: &foregroundShow,
}

• You can set it to false like that:

foregroundShow := false
msg.Message.Android.Notification = &hms.AndroidNotification{
	ForegroundShow: &foregroundShow,
}
