bug fixes!!

• fixed the snails not saving bug
• added a "!" notification when you get an achievement
• visual clarity of the snail in the skills page
• key for seasonal pea to snail conversion
• also! snail compensation for players who:
  • had received snails from an achievement
           BUT
  • did not buy any skills
  if you did not buy skills, but had achievements, you will get 10 free snails as compensation for snails lost :)
