Fixed definitions of flags for some blocks

Fixed some definition errors:
* All these blocks where flagged as "cube solid", but are not:
 Bed, Slab, Stairs, Chest, Farmland, Doors, Ladder, Fence, Cake, Repeater, Trapdoor, Iron Bars, Glas Panes, Ender Chest, Cobblestone Wall, Daylight Sensor, Hopper
* The "Redstone Lamp" is transparent when active.
* Block 74 is lit_redstone_ore = Restone Ore (glowing)
* Block 150 is an active Redstone Comparator.

Also changed to "normal" JSON formatting. This will help much comparing version changes with diff tools. Probably enables non coders to be able to update definitions from wiki information.
