[PATCH weston] introduces a setting to give permission to any client to do screenshots

[Sebastian Wick]

This patch adds a screenshooter section with the "restrict-access"
setting which is on by default and is the current behavior of weston.
When turning it off, all clients can use the screenshooter protocol.
This makes screen capturing for clients easier because they don't
have to be started by weston.
