New description:

 The sloane_find command, which parses output of a webpage, is broken for
 years due to the Sloane sequence webpage being rewritten. It silently
 always finds nothing.

 {{{
 sage: sloane_find([1,1,2,3,5,8,13,21], nresults=1)
 []
 }}}

 The aim of this ticket is to propose a new interface with OEIS

Comment:

 There is a room for lots of improvements, but i submit it now under the
 social pressure ;)

 Most tests use an internet connection, so do not forget
 `--optional=sage,internet` when testing.

 The name of the method `.natural_object()` might be improved (`.sage()` is
 not better since an OEIS sequence is already a Sage object).
