SB Live24-External better handling

Hi.

This patch improves support for 'SB Live 24-bit Extarnal' USB card.

1) This card can go into muted state when a headphones connected or disconnected. So notify mixer about changes in headphone jack.

2) Add LED controls and procfs support just as in similar Audigy 2 NX card.

3) Rename 'PCM Capture' conrol to 'Mic Capture' to reflect reality:
the card may adjust microphone input level only.

Thanks for the patch.

The patch looks fine (except for tiny coding-issues, which I fixed already on my tree).

Could you give your sign-off to merge to the upstream tree?
