[FIX] base: properly check werkzeug version

Werkzeug version was being checked to avoid passing quote=True to
werkzeug.utils.escape (as that parameter was changed to `True` *and
deprecated* in 0.9).

However because DeprecationWarning was made silent by default in
Python 3.2 and the way the check is implemented worked for 0.9 it
looks like nobody really noticed it's broken in the usual manner of
half-assed version checks: works for 0.9.0, doesn't work for
0.12.3 (because lexically 0.12.3 < 0.9.0).

Fix by using proper version parsing and comparing the result of that.
