Redstone++ [16x]

MC 1.13:

= Nothing changed effectively, just reformatted to be compatible with Minecraft 1.13

revision 3:

+ Added inventory icons for comparator/repeater/hopper
- Removed the stone extension, as it is no longer relevant

revision 2:

+ Added new models and textures for hoppers, with clear direction indication!
+ Added new textures for cauldrons, with a nifty state indicator
= Tweaked sticky pistons (more slime on the sides!)
= Tweaked sides of dispensers/droppers to make them even more distinct at distance

revision 1:

+ Added further distinction between different sides for dispenser/dropper/piston
+ Added state indicators for piston/lever
= Lightened textures to mesh better with default stone
- Removed the custom cobble/stone textures from the base pack (still available as an extension pack)
