Calling `gdsdk.openConsole()` multiple times makes buttons unresponsive.

[jespertheend]

When you call gdsdk.openConsole() when it is already open, it opens a duplicate console for which the buttons don't do anything.

I'd like to automatically call gdsdk.openConsole() after initialization so that new developers automatically get the debug buttons in development builds. But since it automatically opens when you refresh the page, you'll end up with broken buttons when doing this.
