base64 encoding and http post

Added base64 "ascii armor" encoding, now the audio data can safely pass over http. Sniffing on the server, I can see the http post. However my server side code is not recognizing and responding to the post yet. talkLock.java.newest is the current source for the client, and there is a build as well, at http://marmot.dudeabides.net/talkLock. The server side code is talk.php. Right now the server is hardcoded to marmot. If you have cgi or php experience, now would be a great time to jump in! Grab the sources and take a whack at it!

As soon as I get the data to post, I will put another release in the download area here on SourceForge.
