Title: Use `nextversion` for generating next version string.

Version string has a rule (PEP 386). It should be followed when suggesting new
version string.
`nextversion` module (https://pypi.python.org/pypi/nextversion) generates PEP
386 compatible version string, so it seems to be good idea to use it.
