libssh2 0.18

I stole some time from my family this weekend and I managed to put together and released a fresh libssh2 tarball, labeled 0.18.

I’m not really too fond of spending a lot of time with a sub-zero version number, but the recent releases have felt like just minor improvements to the previous so bumping up to 1.0 has a certain mental brake all over it. I guess I need to just ignore the brake and take the plunge soon, as I believe it’ll make users more likely to start actually using the lib and that will be good.
