Polylogger

Latest features in this release:
- Clicking on user links outside the app will now open user pages inside the app.
- You can now add dormant languages in the settings tab. This allows you to hide languages that you’re not currently studying in your statistics.
- You can now see other user's stats by navigating to their profile and clicking "see stats".
- Fixed an issue that caused custom google urls to fail when using google login and sign up.
