test program to demonstrate the bug

With a simple DataGridView using default text cells, entering a cell a second time causes a crash due to using an object that has already been disposed.  This is due to DataGridViewTextBoxCell storing an internal private cell editor object that is disposed by DataGridView changing its EditingControlInternal.  The attached program illustrates the problem.  It runs fine on Windows using .Net, but crashes as described on Linux running Mono.
I have a simple fix for this that I will post as a pull request shortly.
