Complete rewrite of the plugin

[BitcoinMitchell]

After months of using the payment plugin for my store, I've decided that it was about time to refactor/rewrite this plugin. It had a few issues and felt messy.

Some of the changed I've done:

• PrestaShop 1.7.7.0 and up is now required
• PHP7.3 is now required as this is now fully supported
  • PHP7.2 is EOL and should not be used anymore
• Setup a proper development environment
  • Also added example IPN callbacks for testing purposes
• Improved the readability of the IPN
  • It's still not perfect, but should be better
• If a cart changed with an existing BTCPay Server invoice, you were redirect to that (now outdated) one
• Improved the backend styling and overal layouts (front- and backend)
  • Also added a tab in the backend, so you can go from Payments directly to BTCPay
• Added GitHub flows so we have at least some linting
  • Also added automated release building
• Updated all the Markdown files with more up-to-date information
• Changed code related to URL generation to use Prestashop generators
• Ensured there is a proper image displayed when showing the Bitcoin payment method
• Hardcoded some constants that were used all over
• Order statuses no longer have fixed ID's
  • They now also have proper images
• Changed the database columns to be a bit more logical
• Added invoice_reference to the database
  • It's used in the BTCPay Server callback URL, so we can always fetch the proper invoice/order for a guest
• BTCPay Server token label is now the name of the shop (if you haven't set one yourself during the process)
• We're now using the official BTCPay Server PHP library (and not the forked BitPay one)
• Added a lot of extra comments to make the code more readable (for myself and others)
• Resolved an invoice redirection issue which caused customers to go to an expired invoice
  • This was due to the facade not being set in the BTCPay Server token that was created
• Changed the config names to be all caps which seems to be the norm for Prestashop modules
• Probably more stuff that I forgot about...

I'm now looking for a PrestaShop developer that uses the BTCPayServer plugin to review these changes. If you are just using the plugin, you're also free to test out the plugin.

It's a lot of code and I do apologize for that.

Since v3 is already tagged, maybe I should change the module version from 3 to 4. 🤔

EDIT: Module version has been tagged as v4 with the update to PrestaShop 1.7.7.0.
