Fixed the build
Replaced Console.Write with Debug.Write

Also did some small groupchat audio stuff
Quick and dirty implementation of audio groupchats

Haven't had a chance to thoroughly test this yet but at least receiving
audio should work well.
Support single and dual channel audio at the same time

Groupchat audio still needs testing.
Don't allow creation of multiple audio groupchats for now
Added support for group titles
Added a default status message
Fixed playback of single channel audio
Fixed sending audio to groupchats
Default text for the 'change group title dialog'
Warn about dns lookups when using a proxy
Started adding support for filter_audio
Update README.md

Moved a section
Audio filter implementation should be done now
Update README.md
Simplify friendId/message check

The original check uses double negation and is overly complicated.
The modified check, while easier to understand, fulfills the exact same
function.
Add tooltips to the checkbox settings

A short sentence about what a specific setting does would help new
users to better understand them.
Merge pull request #23 from UrbanCMC/master
