allow config overlays

tags: 1.5 feature

You can specify wildcards in section titles.

    commands=py.test {posargs}
    use2to3 = True

    deps =

Configuration values are now looked up in a stricter-matches-first
manner: If environment "py32" is considered then first the 
section under py32, then py3*, then testenv. 

support 2to3 configurations / test file postprocessing

tags: 1.5 feature

Tests should be copied and transformed before being executed.
Setup a test definition::

    commands=py.test {posargs}
    use2to3 = True

would transform all specified test files for all py3 environments 
such that a subsequent test run::

    $ tox -e py25,py32 testing/

causes a transformation of the test files to prepare test runs on
Python3 interpreters.  The ``posargs`` specified files will be rewritten
to point to the transformed test files.

allow user-specific python interpreters

users should be able to define their set of python executables
to be used for creating virtualenvs.

non-cached test dependencies

if there is a dependency on a URL whose content changes
the download-cache mechanism will prevent it from being reloaded.
Introduce a 'nocache:' prefix which will inhibit using the cache.
Also make and document a guarantee on the deps order so that
one can influence the exact configuration (e.g. use a dev-version
of some package which a later dependency or the original
package depends upon - i.e. deps should be installed first).

test and make "in-pkg" tests work

it is common to put tests into pkg subdirs, possibly
even with an __init__.  See if/how this can be made
to work.  Maybe also re-consider how py.test does its
importing, maybe add a pytest_addsyspath(testmodule)
and look how nose does it in detail.
