TeamSpeak Client 3.0.1 (64-bit)

- On machines that have a center speaker (like surround 5.1 and surround 7.1) changed the output channels for 1 channel sound to front left+right speakers (was center speaker). This fixes issues for people who have no center speaker connected even though their sound card is configured for surround sound.
- Fixed "Assertion channels==0".
- Fixed UTF-8 usage in plugins API, stylesheets, package installer, soundpacks and updater.
