Fix websocket handshake memory leak bug

There was a problem using openssl's base64 encoding function, there were
some unexplained memory leak problem with the library, so instead of
using openssl, I have decided to just include a base64 encoding function
into wire. Initial testing seems to suggest the problem has been
erradicated.
Merge branch 'master' of github.com:chutsu/wire
