Title: Defining version for pip 1.4+

PIP 1.4+ treats version numbers which aren’t compliant with PEP426 as pre-releases, and won’t use them… `phonenumbers` uses such version numbers.

Setting a similarly non-compliant version gets around this (feel free to propose an alternative version to compare with).
