Rather of calling .exists() synchronously for all documents, use
ShellDocSystem's async API to only stat docs we're showing.
Use the doc opening functionality in ShellDocSystem.
Also, more intelligently do redisplay(); don't recreate actors
for recent docs if we already have one for that URI. We may
need more intelligent caching here; if e.g. just the associated
application changes, we should probably reread the info.

This should not be required, since glib correctly deals with such
applications by giving them the local gvfs path, and those
applications which do support URIs keep being able to use the URIs in
GFiles.

The design has smaller icons in two columns. Add a new
custom display to docDisplay for it.
Clean up some of the texture cache handling for recent URIs so
it's not size-dependent, since the dash size is now different
from the default GenericDisplay size.
Extend ShellTextureCache by adding the concept of a policy, which
we expose to the public API for loading URIs.
This lets us have the shell tell the cache to keep the information
icon texture around forever.
Secondly, fix the caching of recent info; we shouldn't always be
loading the backup pixbuf. Move recent info loading entirely
into ShellTextureCache.
Move thumbnail creation into ShellTextureCache. It's now asynchronous,
and we cache the result.
Create a DocManager class which keeps around the DocInfo objects between
invocations. This is also where we ensure we remove thumbnails for
recent items not known anymore.
Clutter no longer allows using a clone of an actor that is not a part of
the scene graph. This is what used to happen when we created a clone for
the icon of the item that was being dragged, and then closed the More panes
with the original item, removing the icon from the scene graph. This was
also when happened when the user hit Esc while dragging, which prompted the
overlay to close, removing the original icon from the scene graph.
Rename getIcon() methods to createIcon() to better reflect on the fact that
a new icon is created each time the method is called (we do use cache in
some cases).
Remove a stray log message in overlay.js

and http://bugzilla.gnome.org/show_bug.cgi?id=585489
We achieve this with two changes:
- Move the Shell.get_thumbnail call in DocInfo from _init
to getIcon, so that it isn't executed until it's actually
needed.
(If caching the output of said call permanently is desired
we could still do it on the first getIcon invocation, but
I don't believe this is necessary given that looking up an
already generated icon is pretty fast and this also gives
us an updated icon in case the file changes.)
- More importantly, we ommit the get_thumbnail call in case
the URI doesn't start with file://. Looking up, for example,
an http:// URI is very slow, and doesn't give us an icon anyway.

This lets us share the recent-app-tracking, recent-file-tracking, and
icon-drawing code between the overlay and the sidebar, without the
sidebar having to poke into AppDisplayItem and DocDisplayItem's guts.
