Support for Ubuntu 16.04

[sszwed]

I am not able to build latest stable version (0.5.0.62) on Ubuntu 16.04.

Build output (after first fail with the same exception):

Execute of command from this file is failing: docs/CMakeLists.txt. In my system failing command looks like this:

../build/nscp client --module PythonScript --no-stderr --settings dummy --log error --log oneline --load-all --log error --define "/paths:module-path=./modules" -- execute --script scripts/python/docs.py --input docs --output ext/docs

In Ubuntu 14.04 build works fine, so I tied to build there binary and run it in Ubuntu 16.04. It turn out that I missed only two dependencies: libprotobuf and libboost. I updated first package and I still was able to build nscp. After update of libboost I've got the same exception as in Ubuntu 16.04.

Sadly this seems to be due to a bug in boost 1.58: https://bugs.launchpad.net/ubuntu/+source/boost1.58/+bug/1600345 (introduced here boostorg/python@fe24ab9 ) so nit sure how to work around it...

Here's how the LinuxCNC project worked around the boost execfile bug, since we needed to be portable to affected versions: LinuxCNC/linuxcnc@b3ec66b
