Lowering the bar Proposed achievements

We're looking at creating a set of 'achievements' , per the discussion in #1135: https://github.com/onivim/oni/issues/1135

The goal for achievements is to improve discoverability - making it easy for users to find new functionality they might not have been aware existed in Oni.

Here's a few ideas for achievements:

• Welcome:
  • Open Oni for the first time. (This will show users that achievements are part of the editor).
• Tinkerer
  • Edit configuration successfully.
• Vimfidel
  • Use the mouse in Oni.
  • Use arrow keys in Oni.
• Sneaky beaky
  • Open sneak mode
  • Sneak into an explorer window
  • Sneak into a browser window
• General relativity
  • Set relativenumbers
  • Use a relative linewise motion 5x

Would ❤️ to see some other ideas!
