(devel/R-waldo) Updated 0.2.5 to 0.3.0, make test passes

# waldo 0.3.0

* `compare()` is now considerably faster when comparing complex objects that
  don't have any differences (thanks to strategic use of `identical()`) (#86).

* `compare()` gains two improvements to low-level diffs:

    * Structurally identical data frames (#78) and numeric matrices (#76) gain
      a row-by-row diff that makes it easier to see where exactly values differ.

    * An element-by-element diff will be automatically used if it's shorter than
      the "smart" diff. This improves diff quality when comparing two \ 
vectors
      that aren't really related (#68).

* `compare()` gains a `list_as_map` argument thanks to an idea from @dmurdoch.
  It allows you to compare the behaviour of two lists when they are used to
  connect names to values (i.e. the list is operating as a map or dictionary).
  It removes `NULL`s and sorts named components (#72).

* The objects involved in `compare()` (as opposed to the caller of `compare()`)
  gained much greater ability to control the comparison.

    * Objects can now contain a `waldo_opts` attribute, a list with the same
      names and valid values as the arguments to `compare()`, which overrides
      the default comparisons (@dmurdoch).

    * `compare_proxy()` is now called earlier (before type comparison) making
      it more flexible (#65).

    * `compare_proxy()` gains a second argument, `path`, used to report how the
      proxy changed the object. This makes it easier to see when and how a proxy
      is used (#73).

    * Proxies now exist for comparing RProtoBuf objects, converting them to
      proto text format (#82, @michaelquinn32).

* Comparing a list with symbol to a list without that element no longer errors
  (@mgirlich, #79).
