SimpleIDE: Open terminal prevents other SimpleIDE instance using the same port for loading to Propeller

[GoogleCodeExporter]

If multiple SimpleIDE windows are open, one SimpleIDE Terminal will prevent the 
other instance of SimpleIDE from being able to load a program using the same 
com port.  

A) What steps will reproduce the problem?

  1. Open up two instances of SimpleIDE in Windows.
  2. Write programs that display in the terminal for both SimpleIDE instances.
  3. Set both SimpleIDE windows to the same COM
  4. Click Run with Terminal in in the first instance.
  5. Do not close the first instance's SimpleIDE Terminal.
  6. Click Run with Terminal in the second instance.

B) What is the expected and actual behavior (output)?

Actual: "error: opening serial port 'COM**'".  

Expected: The actual behavior really is the one we would expect.  However, some 
customers running multiple SimpleIDE instances might get confused.  It would be 
nice if SimpleIDE could detect that there's another instance already using that 
COM port and suggest that the user find and close that connection.

C) Classify the bug as one of the following:

1. Show Stopper
