Trapped Button

This block idea is to create a fun way to secure/endanger content placed in chests. And open up a world of possibilities! :) 

Core idea:
A button that can warm up if placed nearby magma, and can cool down if placed nearby ice. If placed on or below a dripstone block connected to lava, or water in a cold biome, would also work too.

It would have the following functions:
- act as a regular button if not powered
- emit light radius 1 if in warm mode
- if powered by a redstone cirquit it would be pressed and remain pressed till depowered (to enable using the button without taking damage)
- when in warm mode, it will deal fire damage when pressed manually
- when connected to a block containing other blocks (for example chests), and in warm mode, it will destroy all content not resistent to lava/magma.
- when connected to a block containing other blocks, and in cool mode, it will lock the content in place, unless it is warm of itself (like a bucket of lava, or magma), and turns water buckets into ice over time.
