Inspired from fabianwennink's icon captcha. Although fabianwennink's icon captcha works nicely, there was some modifications to be made. The modifications are listed below:
- Starting with not capping the icon amount, automatically calculating how many icons are there in the user's set folder.
- Instead of having just 1 icon that needs to be selected, I modified it to have 2.
- Instead of requesting each icon separately, we generate a sprite so that the front-end only needs to load the icons once.
- Made noise of the icon more controllable, instead of it being capped to a limited amount (which was originally 50).
- Addon is now more static website focused, meaning it's easier to integrate into websites that do not use JavaScript.
- Remove flex styling to support older browsers
- Make the amount of icon's modifiable
- Automatically generatable captcha, instead of c+p the current code in.
