Set version to 1.0.22

Traditionally Python Unidecode followed the versioning scheme used by the
original Perl module. This doesn't make sense any more because:

1) Perl Text::Unidecode itself switched to a different versioning scheme long ago
http://search.cpan.org/~sburke/Text-Unidecode-1.30/

2) Python Unidecode has now sufficiently diverged from Perl version so that
matched version numbers are no longer useful,

3) setuptools (>= 8) began mangling version numbers, yielding confusion because
Unidecode 0.04.x now sometimes appears as 0.4.x
