Remove lbind.hh

Wasn't being used and it was a mess of code, so it's gone.
Remove OpenSSL dependency.

Wasn't being used and it made building the library a pain in the neck.
Relicense libsnow-common under the Boost Software License, v 1.0.

Doing this because public domain is actually more confusing.
Version 0.1.0

Just because I removed some things.
