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: Remove leading G from filenames

#include <LibGUI/LazyWidget.h>
LibGUI: Add GLazyWidget, a convenience widget for lazily-built UI's Here's how you can use this to speed up startup time: auto widget = GLazyWidget::construct(); widget->on_first_show = [](auto& self) { self.set_layout(...); ... }; Basically, it allows you to delay building the widget subtree until it's shown for the first time.

Everywhere: Rename ASSERT => VERIFY (...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED) Since all of these checks are done in release builds as well, let's rename them to VERIFY to prevent confusion, as everyone is used to assertions being compiled out in release. We can introduce a new ASSERT macro that is specifically for debug checks, but I'm doing this wholesale conversion first since we've accumulated thousands of these already, and it's not immediately obvious which ones are suitable for ASSERT.
