Adds a location property to enable applications to select
the captured files names. Locations are handled just like
multifilesink ones
Also disables -Wformat-nonliteral to allow to use non-literals
on g_strdup_printf on camerabin and generate a sequence of
locations for captures.
Adds an bin that is responsible for encoding and saving video
streams to files.
For now it is simply a ffmpegcolorspace ! theoraenc ! oggmux !
filesink bin.
Still uncapable of recording audio.
