Update Simple Comic to a community maintained fork

[boggydigital]

Simple Comic homepage (http://dancingtortoise.com/simplecomic/) used to link to https://github.com/arauchfuss/Simple-Comic. However the last commit happened in Apr 2017 and after a discussion community has created a new modern maintained fork: https://github.com/MaddTheSane/Simple-Comic

Here is the issue where the discussion happened with more details: arauchfuss/Simple-Comic#126

In this PR, I'm intentionally redirecting download and other links to this new community maintained fork. Let me know if there is other information that would help here.

Important: Do not tick a checkbox if you haven’t performed its action. Honesty is indispensable for a smooth review process.

After making all changes to a cask, verify:

• The submission is for a stable version or documented exception.
• brew audit --cask {{cask_file}} is error-free.
• brew style --fix {{cask_file}} reports no offenses.

Additionally, if adding a new cask:

• Named the cask according to the token reference.
• Checked the cask was not already refused.
• Checked the cask is submitted to the correct repo.
• brew audit --new-cask {{cask_file}} worked successfully.
• brew install --cask {{cask_file}} worked successfully.
• brew uninstall --cask {{cask_file}} worked successfully.

“Streamlined” is marketing fluff and does not belong in descriptions.

The documentation and precedents we have are clear. Unless the main repo points to this specific fork as the official continuation (doesn’t seem to be the case) or the fork is so popular it dwarfs the original and becomes the new default (also not the case), this can’t overtake the main cask. We’ll not switch it to some random fork users may not want.

The documentation is also clear that there is a path for this to be accepted, however. Make a new cask named maddthesane-simple-comic and it can be accepted.

@vitorgalvao, that's fair. I'll open a new cask - thanks for identifying the path forward!
