Moved public API classes into namespace tgvoip (CVoIPController -> tgvoip::VoIPController, CVoIPServerConfig -> tgvoip::ServerConfig)
Endpoint is now a class instead of a struct; also, IP addresses are now wrapped into objects instead of relying on in_addr and in6_addr
Full Windows port (Win32 threading + Winsock + WaveOut/WaveIn)
Added support for ALSA audio I/O on Linux (closes#2)
Abstracted away low-level networking to make it more portable
Minor bugfixes
