Boost serialisation support

[ron0studios]

It would be nice to have boost serialisation support in this library.

Quick intro/tutorial to the format here:

It diverts slightly from normal serialisation because of its archive based system of reading/writing - although I think this is still very doable. Boost is also a pretty hefty library.

If possible I'd like to tackle this myself over the following weeks - big fan of the library and would be keen to make a contribution :)

Thanks!

@ron0studios , I remember taking a look at this some two years ago. I am open to a PR along these lines.
