Title: "Plug Now" feature to select the serial port automatically

The common headache of almost all Arduino teacher is to teach about selecting the correct serial port. You may want to teach about the Windows "Device Manager" or to open/close the serial port menu while plugging Arduino.

Here is the solution. You will find the new menu item "Plug Now..." in the "Tools"->"Serial Port" submenu. Click the "Plug Now..." menu item, a dialog appears, plug your Arduino to PC, wait a few seconds, just click "OK". This selects the correct serial port.

Pre-compiled binaries available here.
