`.alert` vs. `alert-block`

Created by: johnnyshields

.alert-block has different paragraph behavior than alert

.alert-block p {
  margin-bottom: 0px;

}
.alert-block p + p {
  margin-top: 5px;
}

I'd suggest to move these stylings inside .alert, as I can't see a scenario / reason why they shouldn't apply there as well. Perhaps .alert-block should purely be a more padded version of alert?
