http POSTs no longer empty; fetching audio

Builds and sources on http://marmot.dudeabides.net/talkLock/ no longer suffer from 0 byte POSTs of audio. There is also a new "get audio" feature to fetch your audio from the server. However, you have to base64 decode your audio data first manually on the server at the moment. The audio does not survive this process, it is being munged during http transfer. More to come.
