Updated project version to 2020.3.14f1

[nicholas-maltbie]

Description

Updated project and library versions. Also changed windows build to use IL2CPP instead of Mono. Added settings to possibly switch for linux and macos as well but can't get them to work when building from windows... yet!

How Has This Been Tested?

Tested building and running the project locally to ensure it works properly.
