devel/py-Jinja2: support staging and do general clean-up
- clarify license (BSD3C)
- do not use easy_install for installation and convert to auto-generated packing
list
- add staging support
- utilize options helpers
- use PYTHON_REL instead of PYTHON_VERSION to build docs for python >= 3.2, not
only for 3.2
- unmute installation commands
- remove inclusion of devel/py-virtualenv/files/py3k-fix-pkg-plist.inc - it's
implemented in bsd.python.mk
- bump PORTREVISION because of package change
