v1.6

This is the state of the binding as originally developed by @danva994 and targeting CSFML 1.6.

Note that the API is totally incompatible to 2.5 and 2.4.1 versions due to simplification of imported names. See b4b35b9

Due to that, use of this version is not recommended unless you are totally locked in the 1.6 version of CSFML, given that upgrading will require massive name changes (though automatable).
