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: 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.

LibGUI: Move index_at_event_position() up to GAbstractView It's now an abstract (pure virtual) public method in GAbstractView that individual widgets have to implement. This will allow us to move more selection-related logic into GAbstractView in order to share it between implementations.
