Generated ePubs failing validation

Hello,

Following on from my latest pull request (#412) here are all the ePub validation failures from trying to export the guide.

That pull request should fix the first three errors. The eleven after it appear to be due to those pages having the quick search widget on them and the start button for it. The next two, along with the two at the end, are broken identifiers in the TOC (probably best to leave these until last). The last error is simply a case of an image being called from another server, but ePub needs all those objects. Fixing this last one just means uploading http://www.python.org/dev/peps/pep-0001/pep-0001-1.png to a suitable location and updating intro/community.rst to use the local version.

Beginne mit epubcheck.sh pythonguide.epub und ordne die gemeldeten generierten Dateien ihren Quellen zu. Überprüfe search.html, dev/virtualenvs.html, shipping/freezing.html, shipping/packaging.html, genindex.html, index.html, starting/install/win.html, writing/tests.html und intro/community.rst. Als erledigt gilt die Aufgabe, wenn die aufgeführten Validierungsfehler von EPUB 2.0, einschließlich der Referenz auf das entfernte Bild, behoben sind.
