Some redstone stuff

I have some propositions: 1. Delayer: Redstone block similar to comparator and repeater. Have his own menu. You can set there delay for example from 0 to 500 ticks. Useful in delayed mechanism, for example delayed redstone doors. 2. Vertical redstone: (don't even need description) 3.Charger: Block, that after powering from one side makes big redstone signal (for example 30) from another. Have input and output side. May need powering from above or down to work. 4.Extensible piston: Basically works like normal piston. But after adding piston extension (craftable somehow with wood) from back, you can extend piston work up to for example 10 blocks. Useful for example in small elevators. Have also sticky version.
