Try ubuntu trusty

[axman6]

Working in this branch until I can get travis working.

This is probably a dead end, once we find a proper fix I'll delete this, but it might be a good place to experiment in the mean time

@Deguerre I think I've got travis working as far as I can without delving into the C++ side of things, if you get a few minutes would you mind having a look at the failing build on travis? Excerpt from the build:

Once this is all sorted, I'll add the covered build status icon to the README =)

That is precisely the issue I had building on Ubuntu 14. The default boost is build with the old (pre-C++11) ABI.
