Forked v2 for uvcc

[joelpurra]

In order to progress with uvcc, I am using a forked uvc-control based on master (https://github.com/makenai/node-uvc-control/commit/ca1e2c963e98b309ad3b65c5fc538f052ea5fd64). There are bugfixes and improvements to get feature-parity with uvc-control v1. Might add new stuff if deemed useful.

It'd be better to have everything merged to (and published from) uvc-control, so here's a pull request for tracking progress. It'll be a draft for now; can be split into multiple pull requests later if changes are of interest.

See uvcc, which wraps uvc-control in a command line tool.
