#1381 Don't show "python not configured" error in explorer

[Anonymous]

After I accidentally opened a python file my C++ project explorer now shows a large error marker saying "python not configured". I don't use PyDev on this project, I'm working on C++ and only accidentally opened a python file. I don't want to be nagged into configuring a tool I don't use. Also, the C++ project explorer is not the place to display error messages, there are numerous other more appropriate places in eclipse -- the problems view comes to mind.
