Run without Debugging (Ctrl+F5) should be allowed even for targets that don't support debugging

[joshtynjala]

If the Neko target is selected, Run without Debugging shows the notification "Debugging Neko is not supported". However, I'm not asking it to debug. I just want to launch it, like if I ran lime test neko from the command line.

When choosing Run without Debugging, the debug configuration will have noDebug set to true. That can be used to determine if debugging is necessary or not.
