update release date

add some missing things to the changelog
update MANIFEST.in
make the standalone version work with jython 2.5.3
ignore .class files

Show names with hyphens instead of underscores
...on the "/simple" listing.

On the "/simple" listing page, names with hyphens and names with
underscores are currently both pointing to the same set of files due to
the use of `pypiserver.core.normalize_pkgname`. Make a change to display
only names with hyphens on the "/simple" listing page to avoid
duplication.
