Implementation of a cult visual network, similar to the original camera network.
Includes the "eye" itself and the initial construction of a mob that can control one.
Relocates eye movement to the eye code itself.
Adds a mask that allows any mob able of wearing it direct access to the camera network, as a proof of concept and adminbus.
Now possible to customize chunk obfuscation image per chunk type.
Obfuscation images are stored per type (thus the small datum structure) to reduce memory footprint in the case of multiple chunks using the same image.
