Added API token handling

+ Tokens can be added by the add_token command or via the CLI
+ Tokens are checked for authorization before a command is run
+ Added an error message field to the GeoffreyApiResponse
+ Made tokens strings instead of u64s
  + Tokens are randomly generated 64 char long alphanumeric strings
+ Clippy + Fmt
