Title: make acrylamid/defaults/ a package (again)

`acrylamid/defaults/` is used as a package in various places.
But python needs the file `__init__.py` in the root directory of the
package.
Commit 7826fa16 moved this file away. Acrylamid keeps working if there
is a old `__init__.pyc`, generated from an old `__init__.py`. But
otherwise it crashes with:
`ImportError: cannot import name defaults`

This commit adds an empty `__init__.py` to make python recognize the
package again.
