/***
* Shoutouts:
*
* Bytecode origin https://www.reddit.com/r/ethereum/comments/6ic49q/any_assembly_programmers_willing_to_write_a/dj5ceuw/
* Modified version of Vitalik's https://www.reddit.com/r/ethereum/comments/6c1jui/delegatecall_forwarders_how_to_save_5098_on/
* Credits to Jorge Izquierdo (@izqui) for coming up with this design here: https://gist.github.com/izqui/7f904443e6d19c1ab52ec7f5ad46b3a8
* Credits to Stefan George (@Georgi87) for inspiration for many of the improvements from Gnosis Safe: https://github.com/gnosis/gnosis-safe-contracts
*
* This version has many improvements over the original @izqui's library like using REVERT instead of THROWing on failed calls.
* It also implements the awesome design pattern for initializing code as seen in Gnosis Safe Factory: https://github.com/gnosis/gnosis-safe-contracts/blob/master/contracts/ProxyFactory.sol

Very cheap to deploy (66k gas) forwarder contracts that can clone any contract and still have their own storage

// Forwarder is slightly modified to only return 256 bytes (8 normal returns)
// Deployed Factory in Kovan: https://kovan.etherscan.io/address/0xaebc118657099e2110c90494f48b3d21329b23eb

// Just 66349 gas per contract

Steps to enable GPG signing of git commits.

If anyone is interested in setting up their system to automatically (or manually) sign their git commits with their GPG key, here are the steps:

  1. Generate and add your key to GitHub
  2. $ git config --global commit.gpgsign true ([OPTIONAL] every commit will now be signed)
  3. $ git config --global user.signingkey ABCDEF01 (where ABCDEF01 is the fingerprint of the key to use)
  4. $ git config --global alias.logs "log --show-signature" (now available as $ git logs)
  5. $ git config --global alias.cis "commit -S" (optional if global signing is false)
  6. $ echo "Some content" >> example.txt
  7. $ git add example.txt
  8. $ git cis -m "This commit is signed by a GPG key." (regular commit will work if global signing is enabled)

A script for Ecwid to display the 'Preorder' label instead of 'In stock' when a product has unlimited stock quantity
