Initial unified v56.1 release for all platforms / pythons / architectures

[cztomczak]

This will be the first unified release that includes packages for all platforms (Windows, Linux, Mac), all python versions (2.7, 3.4, 3.5, 3.6) and all architectures (32bit, 64bit). The only exception is Mac which doesn't support 32-bit anymore.

Support matrix

OS	Py2	Py3	32bit	64bit	Requirements
Windows	2.7	3.4 / 3.5 / 3.6	Yes	Yes	Windows 7+
Linux	2.7	3.4 / 3.5 / 3.6	Yes	Yes	Debian 7+ / Ubuntu 12.04+
Mac	2.7	3.4 / 3.5 / 3.6	No	Yes	MacOS 10.9+

Creation of this release is fully automated with the automate.py and build_distrib.py tools. The build_distrib.py tool generates all possible packages for pythons / architectures. Linux doesn't support chroot , so 32bit is built separately in VirtualBox.

Windows and Mac are using CEF binaries from Spotify Automated Builds. Linux is still built from sources and that will soon change, when our patches are merged in upstream.
