[split] CodeIgniter 3.1.11 Released vs CI4 Rants

@captain-sensible,
I agree about making availability of CodeIgniter's downloads and installs as simple as possible.

Unfortunately CodeIgniter4 requires a couple of essential settings to prevent the initial and unhelpful failed screen. I would prefer a successful splash screen regardless of settings. Hopefully this would encourage new users to investigate new features.

I used to use the zip option but now find the "git clone (dowload link)" far easier, just delete the previous version, install the latest tweak a couple of settings before ensuring the steps were successful.
