Created a new class Component::SafePointer that keeps a pointer to a component and automatically nulls it if the component is deleted - this makes it a much more elegant replacement for the old ComponentDeletionWatcher class. Removed Component::getComponentUnderMouse(), which doesn't fit with multi-touch interfaces - for similar functionality, use the Desktop::getMouseInputSource() methods to find out what MouseInputSources are available, and ask them about the component they are over or dragging.
