Removed an unnecessary include in cAudioManager.h
Added a define to set the number of buffers used by an audio source
Added the last of the previously unsupported OpenAL source parameters (Cones, attenuation tweaking, max/min volume, and rolloff factor)
Cleaned up the implementation of cAudio source. It no longer keeps a redundant copy of the state information and functions are now in order that they are defined. Some functions have been renamed to be clearer.
Other changes throughout the code to support the changes to the cAudio source.
Changed song used by Tutorial1_2DSound.
Added some comments.
Changed cVector3 to use a custom Episilon instead of including float.h (less bloat)
Added debug log entries to cAudio
Allowed cOggDecoder to return error values from decoding. cAudio now handles those errors a little better.
Updated logger to allow a user to create callbacks to receive log messages
Logger also gives more information, time the message was sent, the source, the importance, and the message itself.
User can now query playback devices and specify the device for the audio manager to use. The audio manager is no longer a singleton, although creating multiple managers is not advised.
Clean up and optimization of manager initialization code.
IAudioCapture can now be told which device to capture audio from. The user can also create multiple IAudioCaptures to capture audio from multiple sources at the same time.
Added additional error checking.
A seperate thread is used to capture audio now.
Defines added to allow a user to remove support for default codecs.
Made cAudio, cAudioCapture, cAudioManager and other classes thread safe.
Made cAudioManager use a seperate update thread by default.
Added cAudioSleep, a cross-platform sleep() function
Moved global defines to cAudioDefines
Added defines to disable thread safety or the internal update thread if the user wishes it
Updated tutorials to reflect the changes made
Added a raw audio decoder, allowing raw audio to be played if the format and frequency is known. Will also load from .raw files on disk, but will assume the format is 16 bit mono and the frequency is 22050 hz
Added a tutorial to show how recording and playback can be done.
Added the ability for the user to unregister audio codecs that they will not be using. Also added methods to test for the existance of a decoder and get the decoder factory back.
Moved cVector3.h to include instead of Headers to make using it in user projects easier (one less include path)
Moved the audio format enum to its own header file.
Small fix in the wav decoder to prevent the file header from being played as audio data.
