[Hotfix] Bug + Easter Eggs

Hi All!

This should have been done weeks ago, but ¯\_(ツ)_/¯

Anyway, small update [V2.0.1]

• Added the English translation to some buttons and links (it was not breaking gameplay, but I missed those bits)
• Fixed the issue with the Sudoku time result when solved.
• Added some alt text to as many images as I could (does not include icons)
• Added an Easter Egg popup on the last screen of the game, with the list of all references

The only thing missing for this project to truly come to a close is a proper post-mortem.
But again ¯\_(ツ)_/¯ who knows when I'll have the time....

Thank you to each and every one of you who have played this game, and rated it, and reviewed it, and commented about it!!!
