Cyclic

New feature with cables: hide them using solid blocks with a feature called 'facades', just sneak-left-click a block onto the cable (empty hand to remove it); this does not use any items and can be managed/disabled in the config file.

Renamed 'Concentrated Glowstone' to 'Glowstone Facade' and 'Concentrated Soundproofing' to 'Soundproofing Facade'.
Fixed issues with both blocks to correctly render facades (use sneak-left-click while not in creative), and they no longer have an inventory.
