common changes:
 - strip Makefile header
 - choose proper value for USE_PYTHON in a cases when I sure that the port
   is required -2.7 only or may be built/run both 2.x and 3.x
 - comment off USE_ZOPE
 - tab -> space in pkg-descr:WWW

nuances:
 - new port www/py-plone.app.jquery added per this plone update requirements
 - devel/py-zope.schema updated to 4.2.0 because I hadn't got any response from
   maintainer and because this exact version is required for this plone update
