Release of v1.0.0b1

First (development) release of the fork PodGen!

MASSIVE changes have been made, and this version
is NOT backwards compatible with python-feedgen.
Changing your code so it is compatible with
PodGen requires that you rewrite all the code
that uses the library. As such, you are recommended
against switching until the first stable release
is ready, since the API may change until then.

See "Why the fork?" at https://podgen.readthedocs.org
for a more elaborate description of the changes and
reasoning behind this fork.

In general, head over to https://podgen.readthedocs.org
