Clean up and update

[dolichomps]

Sorry for my commits being all wacky.

Here is what I changed: Updated google play service version Removed GodotSQL dependency Removed need for google-services.json (firebase) Removed links and dots appid from ids.xml Updated readme Added a .gitignore Fixed an issue where submit_leaderboard was returning the wrong values in logcat with frogutils

• This also fixed an issue with the leaderboard not submitting (but that may have been an issue isolated to me) Updated copyright Fixed performance and security warnings brought up by gradle lint

I'll pick some commits from this PR as I am working on a version where all four modules of FrogSquare works together. I need some time before doing so.
