Asyncrhonously fetch all relevant EClient instances during instance
initialization to try and get them cached ahead of time, and so that
all status icons are present when the tree view is shown.
The results were postponed to show as long as there were new notifications
about added contacts, which could take quite long for many matched items.
This shows the results with smaller timeout and without postponing.
Append a tree view column to display a symbolic icon hinting at backend
status. Currently this only displays icons for online/offline and when
the backend dies. I'd also like to add a spinner icon to indicate when
we're processing a query and for other long-running activities.
Returns TRUE if an EClient instance for the given source and the value
of ESourceSelector's "extension-name" property was recently discarded
after having emitted a "backend-died" signal, and a replacement EClient
instance has not yet been created.

WebKit deny in loading local URIs (file://...) when an HTML body is
constructed from a string, not from a local file, thus fix the URIs
into "evo-file://", which are passed into our request handlers,
which can load the local files.
EClientSelector extends the functionality of ESourceSelector by
utilizing an EClientCache to display status information about the
backends associated with the displayed data sources.
(No backend status is displayed just yet, but that's the plan.)
Changed my mind. There's some scenarios where a function depends on an
ESourceRegistry but could also utilize an EClientCache, and it would be
nice to just pass the EClientCache and extract the ESourceRegistry from
it, so we need to make sure the ESourceRegistry will be there when it's
needed and not quietly disappear.
