Automatic builds

[heyLu]

Even though we have an automated docker build now, it's still a bit tricky to build tricky pixie locally.

We should be able to build it in a docker container and then upload the built version as a release on GitHub. However, we'd need to figure out how to crosscompile and statically link pixie and it's dependencies.

Here are some resources that might help:

• portably-pypy, used for the portable linux builds of pypy
  • a centos 5 docker image
• GitHub's Releases API

from what i remember, rpython has pretty shitty cross compilation support.

What about using something like Opensuse Build Service?
