Fix T47064: Change Audio defaults to 48 kHz

Historically blender had an audio sample rate of 44.1 kHz as default which is mostly popular because it's the sample rate of audio CDs. Audaspace kept using this default from the pre 2.5 era. It was about time to change to 48 kHz, which is a more widespread standard nowadays, especially in video. It is the recommended sampling rate of the Audio Engineering Society.
