Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

LibGUI: Implement nested event loops to support dialog boxes. This patch adds a simple GMessageBox that can run in a nested event loop. Here's how you use it: GMessageBox box("Message text here", "Message window title"); int result = box.exec(); The next step is to make the WindowServer respect the modality flag of these windows and prevent interaction with other windows in the same process until the modal window has been closed.

Add clang-format file Also run it across the whole tree to get everything using the One True Style. We don't yet run this in an automated fashion as it's a little slow, but there is a snippet to do so in makeall.sh.

LibGUI: More work on GInputBox. - If the GInputBox has a parent and the parent is a GWindow, center the input box window within the parent window. This looks quite nice. - Stop processing events in a nested event loop immediately after it's been asked to quit. - Fix GWidget::parent_widget() behavior for non-widget parents.

LibCore: Put all classes in the Core namespace and remove the leading C I've been wanting to do this for a long time. It's time we start being consistent about how this stuff works. The new convention is: - "LibFoo" is a userspace library that provides the "Foo" namespace. That's it :^) This was pretty tedious to convert and I didn't even start on LibGUI yet. But it's coming up next.

LibGUI: Close and cancel GDialog on escape This is a small usability enhancement. If you press escape with a GDialog focused, it will now return its "Cancel" status.

LibGUI: GDialog should close its nested event loop on window close. Make GWindow::close() so we can override it in GDialog and quit from the internal event loop when the window manager tells us to close ourselves. The dialog will return GDialog::ExecCancel in these situations.

LibGUI: Don't use Core::Object::add() to instantiate dialogs Now that add() returns a WidgetType&, we can't rely on the parent of a GUI::Dialog to still keep it alive after exec() returns. This happens because exec() will call remove_from_parent() on itself before returning. And so we go back to the old idiom for creating a GUI::Dialog centered above a specific window. Just call GUI::Dialog::construct(), passing the "parent" window as the last parameter.
