API Changes/Deprecations

A few breaking changes were made in the API, this will likely be the only instance of this during 5.x's lifetime:

• PlatformSource#console is now PlatformSource#server to better reflect intention
• PlatformSource.Factory#entity --> PlatformSource.Factory#fromID

As for deprecations:

• Account methods within the Economy API reflecting balance states or interactions have been deprecated in favor of async alternatives.
  • This change was made in order to better favor designs which might be based on a database or even a request manager to ensure stateful interactions are allowed
