Initial commit
-fixed message sent alert giving NaN instead of the number os messages sent
-finished appointment system with 4 states only (0 - in line, 1 - sending, 2 - completed, 3 - cancelled) - This means that you cannot make the system pause the current sending process to start an urgent one, you can only cancel it. The urgent means - "Next in the queue".
