[Qt-creator] Closing project plugins

[Hugo Parente Lima]

Hi,

I did a small QtCreator plugin to handle projects written using my own
build system, the plugin is the most simple project plugin that could
exists, i.e. no build steps, no build configuration, nothing, just the
project files indexed by the C++ code model.

So, here is my problem:

Having a project using my plugin opened into QtCreator if I choose
"close all projects", everything goes as expected, but if I close the
project using the context menu on the Project tree in the left pane,
all editors are closed but the tree nodes remains there, I can even
open the files by double clicking them.

I may forgot something, but after a look into other project plugins I
didn't found what's missing.

The ProjectExplorer::Project derived class can be found here:
https://github.com/Meique/MeiqueQtCreatorPlugin/blob/master/src/MeiqueProject.cpp

Thanks in advance if someone have some ideia where's the problem.
