Stop overriding Rip::Core::*#inspect
Implement Rip::Core::{Object,Boolean}.@.to_boolean
Define System.Boolean.{true,false}
Expose System.Boolean
Define Character in Rip source and expose as `System.Character`
Add very basic test for Rip::Nodes::Invocation#interpret
Test that division with a remainder returns only the whole number portion
Define Integer in Rip source and expose as `System.Integer`
Add another assertion to System.Integer.@.{%,*,+,-,/} test loop
Expose `System.{Boolean,Character,Integer}
