camerabin2: adds location property

Browse source 
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.
