uvccapture: new package

"Capture image from USB webcam at a specified interval"

I apply patches from Debian to make it build with V4L2 (instead of v1
API) and fix some warnings/bugs. Source code is also downloaded from
Debian, as uvccapture homepage is unavailable.

linuxstopmotion: new package

Linux Stopmotion is a program for creating stop-motion animation movies.

I had to apply a small patch to make grabbing images from webcam work
(using uvccapture). I find it odd that it didn't work without the patch,
seeing that Arch Linux also have the v0.8.0 version, but with no patch.
Latest Ubuntu (14.04) has v0.7.2, which is unaffected.
