        Robot Framework with Python 3 compatibility

- Forked from
- Still compatible with all officially supported
  Python 2.x platforms and versions, starting with 2.5
- Not tested with Python 3 < 3.3
- Invokes ``2to3`` in ````, ``atest/``
  and ``utest/`` in addition to manual code changes
- Goal is to make code completely 2/3 compatible without the need for 2to3,
  at the cost of dropping Python 2.5 support

Differences in Python 3

Python 3 makes a clear distinction between ``str`` for textual data
and ``bytes`` for binary data.
This affects the Standard Test Libraries and their Keywords:

- ``str`` arguments don't work where ``bytes`` are expected,
  like writing to binary file streams or comparing with other ``bytes``.
- ``bytes`` don't work where ``str`` is expected,
  like writing to text mode streams or comparing with another ``str``.
- Reading from binary streams always returns ``bytes``.
- Reading from text streams always returns ``str``.

You can use the following keywords to explicitly create ``bytes``:

- ``BuiltIn.Convert To Bytes``
- ``String.Encode String To Bytes``

I extended ``Process.Start Process`` with a ``binary_mode`` argument.
By default the process streams are opened in text mode.
You can change this with setting ``binary_mode=True``.

``Collections.Get Dictionary Keys`` normally sorts the keys.
I disabled key sorting in Python 3,
because most builtin types are not comparable to each other.
This further affects ``Get Dictionary Values`` and ``Get Dictionary Items``.
I still need to find a better solution... Maybe imitate Python 2 sorting?
Any suggestions? :)

Robot Framework

Robot Framework is a generic test automation framework for acceptance
testing and acceptance test-driven development (ATDD). It has
easy-to-use tabular test data syntax and utilizes the keyword-driven
testing approach. Its testing capabilities can be extended by test
libraries implemented either with Python or Java, and users can create
new keywords from existing ones using the same syntax that is used for
creating test cases.
