Change settings form opening as show dialog

Changed settingsForm.Show(); in settingsForm.ShowDialog(); to avoid the possibile to open multiple settings form which is usless. That can create problems if a user doesn't make attention and opens more instances of this form.
With .ShoWDialog() we avoid this problem you must be open just 1 form at time
