Add a DropState enum to the internal state of the sidebar

Browse Source 
We want to show a little animation when a DnD operation is happening and the user hovers
between existing bookmarks.  The animation should indicate the user that he's about to
create a new bookmark from the file right there.

/* These are used when a destination-side DnD operation is taking place.
* Normally, when a file is being hovered directly over a bookmark,
* we'll be in DROP_STATE_NORMAL.
*
* But when a file is being hovered between bookmarks, this means the user
* may want to create a new bookmark for that file between those bookmarks.
* In that case, the drop state will be *not* DROP_STATE_NORMAL.
*
* When the drop state is FADING_OUT, it means that the user is hovering
* directly over an existing bookmark and an immediate drop will cause the
* file being dragged to be dropped on the bookmark, instead of causing
* a new bookmark to be created.
