- Added 1.21 support

1. Added a new placeholders in messages to the section 'buying', the placeholders are: %balance-spent% and %formatted-balance-spent%

1. Removed the check if your inventory is full, made it so if you attempt to buy 64 of an item, and you only have space for 1, it'll change it's price for the amount of money you need to buy that 1, meaning if your inventory is completely full it'll cost you no money but receive nothing at the same time.

Made a check if that happens to send a message that you inventory is full.
You could either regenerate your config.yml by deleting it or add the new message section into your config manually, or it'll just take the default message if you leave it like it is right now.

section that it should be under messages in config.yml:

not-enough-space: '&cYou do not have enough space in your inventory.'

1. Added support for PlayerPoints.
