PictureController and hide default buttons

[z85510]

I used to take pictures by myself but I updated the library and PictureBuilder doesn't exist anymore.

If you want to have your own UI for taking pictures, take a look at our documentation:
https://docs.page/Apparence-io/camera_awesome/getting_started/custom-ui
You may also be interested in other areas of the doc to see what you can do now since there have been many changes with version 1.0.0.
