V 0.5.3.5

I made a silly mistake in the most recent update that prevented all achievements from unlocking.
I have now fixed this issue, and alongside the fix have added a check to see if you've:

• Already been promoted.
  
• Already unlocked 5 upgrades.
  
• Already purchased the dog.
  

All other achievements, I believe, should be unlockable without having to create a new save.
If you notice anymore issues, or believe any more checks need to be made, please let me know and I'll get it fixed
ASAP!
Craig.
