Microphone input implemented.

RecordingDevice class added
(number)love.audio.getRecordingDeviceCount() and (table)love.audio.getRecordingDevices() exposed
(bool):startRecording([samples, sampleRate, bitDepth, channels], (SoundData):stopRecording([SoundData]),
(SoundData):getData([SoundData]), (number):getSampleCount(), (number):getSampleRate(), (number):getBitDepth(),
(number):getChannels(), (string):getName(), (number):getID(), (bool):isRecording() member functions exposed
previously existed stub implementation removed
getFormat moved to love::audio::openal::Audio
getFormat arguments order swapped to (bitDepth, channels)
getFormat now returns AL_NONE if format is invalid
