Snappy webcam-demo is non-functional

Since the webcam-demo package has been revised, the new version is 1.0.1. For example,

sudo systemctl status -l webcam-demo_webcam-demo_1.0.1.service

Furthermore, any attempt to assign /dev/video0 to this application fails with a strange message:

sudo snappy hw-assign webcam-demo.sideload /dev/video0
snappy package not found

Thanks Tim, I've fixed the version.
I'm also adding snappy to the report for that odd issue.

The .sideload references have been replaced by .canonical, since the guide has switched from a local snap to a store one. This fixes the second issue.

I think it's because the original version of the guide was written with a locally-installed snapp, whereas a store snapp was made available afterwards. At least that's what I think. After changing the instructions to .canonical, the guide worked for me
