LibGUI: Add a GItemView class. This is a GAbstractView subclass that implements a icon-based view onto a GModel. It still need a bunch of work, but it's in basic usable shape.

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.

LibCore: Introduce a C_OBJECT macro. This macro goes at the top of every CObject-derived class like so: class SomeClass : public CObject { C_OBJECT(SomeClass) public: ... At the moment, all it does is create an override for the class_name() getter but in the future this will be used to automatically insert member functions into these classes.

LibGUI+WindowServer: Start fleshing out drag&drop functionality This patch enables basic drag&drop between applications. You initiate a drag by creating a GDragOperation object and calling exec() on it. This creates a nested event loop in the calling program that only returns once the drag operation has ended. On the receiving side, you get a call to GWidget::drop_event() with a GDropEvent containing information about the dropped data. The only data passed right now is a piece of text that's also used to visually indicate that a drag is happening (by showing the text in a little box that follows the mouse cursor around.) There are things to fix here, but we're off to a nice start. :^)

GItemView: Add context menu support Also, use the model_column() internally for selection as well as for painting to keep things consistent. Note that we always fire the on_context_menu_request hook, even if you didn't click on an item. In those cases, you get a GModelIndex().

LibGUI: Refine the per-item rects in GItemView Previously we would consider anything in the large padded area around each item to also be part of the item for mouse event purposes. This didn't feel right when rubberbanding, so this patch factors out the per-item rect computation into a get_item_rects() helper which can then be used by the various functions that need it.

LibGUI: clicking and dragging one item will drag other items in selection Previously if more than one item was selected clicking on one of them and dragging would de-select everything that is not the one that was clicked on. Now, if more than one items are selected and there is a mousedown it goes into a "mightdrag" state. The user can then perform a drag, if they don't everything that is not the item being clicked gets unselected in the mouseup event, mimicking the previous behavior.
