tox 1.6.1 uses default pip 1.3.1 -> bad install_command default

Tox 1.6.1 doesn't work out of the box using win32, python33 32bit.

The install_command default is pip install --pre ..., which is unsupported by pip 1.3.1 - the version, which gets installed by tox! I didn't find a possibility to set deps=pip>=1.4.1, which leads to a circular problem, if I want to avoid changing the default install_command! I can't upgrade pip without changing the default. Upgrading itself make the change obsolete.
The default pip version for any environment should therefore be pip>=1.4, if the --pre option is a default!
This was annoying to find for a newbie like me...

This is my working tox.ini, just in case.

#!tox

[tox]
envlist = py33
[testenv]
install_command=pip install {opts} {packages}
deps=
    -rrequirements.txt
commands=
    py.test
[testenv:py33]
basepython=D:/Python33/python.exe

requirements.txt:
pytest

Sorry for the troubles and thanks for going through the effort. Will see to accomodate by either changing the required pip version or something else (need to investigate a little myself).
