Refactor mod to use the new HTTPS API. 

This commit makes several changes:
 ¤ The mod (finally) uses the lurkcoinV3 API.
 ¤ Transactions to non-existent users are reverted (provided both 
servers are using the updated mod)
   · There is a small processing fee on transactions to invalid users 
(definitely not a bug)
 ¤ Fix non-minetest_game formspec prepends on ATM formspecs.
 ¤ Stop overriding minetest.log.
 ¤ Add luacheck workflow based on the one at 
https://github.com/BlockySurvival/bls_custom
 ¤ Fix errors reported by luacheck.
