Plone 4.3 compatibility (import)

The imports were not Plone 4.3 compatible, e.g.:


>from zope.app.pagetemplate import ViewPageTemplateFile
>zope.configuration.xmlconfig.ZopeXMLConfigurationError: File >"/home/lepri/trabalho/observatorio/observatorio.buildout/parts/instance/etc/site.zcml", line 12.2->12.39
>    ZopeXMLConfigurationError: File "/home/lepri/.cache/eggs/Products.CMFPlone-4.3->py2.7.egg/Products/CMFPlone/meta.zcml", line 42.4-46.10
>   ImportError: No module named pagetemplate

I used zope.browserpage.viewpagetemplatefile.ViewPageTemplateFile instead of zope.app.pagetemplate.viewpagetemplatefile.ViewPageTemplateFile.
