[server] Add source_by_eid and source_by_uri methods to repository
Most of the times we only need to retrieve one source (either by uri or eid)
and querying sources_by_eid and sources_by_uri properties on repository just
for one item is costly. So these methods query what's needed. We issue a
ValueError (instead of KeyError for sources_by_{eid,uri} dict) in case the key
is not found.

What's next?
------------
In this tutorial, we have seen that you can, right after the installation of
|cubicweb|, build a web application in a few minutes by defining a data model as
assembling cubes. You get a working application that you can then customize there
and there while keeping something that works. This is important in agile
development practices, you can right from the start of the project show things
to customer and so take the right decision early in the process.
The next steps will be to discover hooks, security, data sources, digging deeper
into view writing and interface customisation... Yet a lot of fun stuff to
discover! You will find more `tutorials and howtos`_ in the blog published on the
CubicWeb.org website.
