Port of msgpack to Chicken 5

[Théo Cavignac]

Hi,


About two years ago I started a big project using Chicken and msgpack. 
The msgpack egg being stalled and only in C4, I ported it to C5.

I tried to contact the original author on Github but he never replied 
(maybe he will see this mail, in which case I would be happy to hand 
over my port to him).

Not having any answer I planned on releasing this myself, but it delayed 
that for some time waiting for a moment to learn a bit more about eggs 
publications.

That day came today.

I never submitted an egg before so I am not sure everything is alright 
but this community is very helpful, so I look forward to make it perfect.

The code is available at https://github.com/Lattay/chicken-msgpack.

I updated the doc and added a README.svnwiki that could be used as a 
wiki page I think.

The release info is there: 
https://raw.githubusercontent.com/Lattay/chicken-msgpack/master/msgpack.release-info

There is a test suite from the original author that I find pretty good.


Cheers,

Théo
