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.

WindowServer: Add API to set/get screen layouts This sets the stage so that DisplaySettings can configure the screen layout and set various screen resolutions in one go. It also allows for an easy "atomic" revert of the previous settings.

WindowServer: Port to the new IPC system This patch introduces code generation for the WindowServer IPC with its clients. The client/server endpoints are defined by the two .ipc files in Servers/WindowServer/: WindowServer.ipc and WindowClient.ipc It now becomes significantly easier to add features and capabilities to WindowServer since you don't have to know nearly as much about all the intricate paths that IPC messages take between LibGUI and WSWindow. The new system also uses significantly less IPC bandwidth since we're now doing packed serialization instead of passing fixed-sized structs of ~600 bytes for each message. Some repaint coalescing optimizations are lost in this conversion and we'll need to look at how to implement those in the new world. The old CoreIPC::Client::Connection and CoreIPC::Server::Connection classes are removed by this patch and replaced by use of ConnectionNG, which will be renamed eventually. Goodbye, old WindowServer IPC. You served us well :^)

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.

WindowServer+LibGUI: Expose raw scroll wheel values to applications This is useful, for instance, in games in which you can switch held items using the scroll wheel. In order to implement this, they previously would have to either add a hard-coded division by 4, or look up your mouse settings to adjust correctly. This commit adds an MouseEvent.wheel_raw_delta_x() and MouseEvent.wheel_raw_delta_y().

WindowServer: Add message to notify clients of applet area resize Applets and windows would like to be able to know when the applet area has been resized. For example, this happens asynchronously after an applet has been resized, so we cannot then rely on the applet area position synchronously after resizing. This adds a new message applet_area_rect_changed and associated Event AppletAreaRectChange, and the appropriate virtual functions.
