RFS updating the setuptools-scm and mistune packages

[Julien Puydt <julien.puydt@laposte.net>]

Hi,

I made the following changes to both setuptools-scm and mistune :
* New upstream release.
* Switch maintainership from DPMT to myself.

Those packages both have their previous versions in testing+unstable.

They are available from here:
ssh://git.debian.org/git/python-modules/packages/mistune.git
ssh://git.debian.org/git/python-modules/packages/setuptools-scm.git

(I didn't tag & dch -r in case a sponsor finds something to change)

Thanks,

Snark on #debian-python
