Implement a base64 converter and put it into its own library. It's named
crypto although it only contains an encoding right now, but later we'll
need more libssl/libcrypto bindings there.
Mark release as 0.2.2.
Merge branch 'libtoolbox-0.2-stable' of github.com:tonnerre/libtoolbox into libtoolbox-0.2-stable
Ok, more version mess. 0.2.3 it is.
