Separate system-level options (No_Load_Modules, Load_Modules, No_External_Scripts, External_Scripts) from library-level options (No_Stdlib, No_IO, No_Prelude, No_JSON) into two distinct enum types. Add Library_Options as a parameter to the ChaiScript constructor. Update tests to demonstrate both ChaiScript_Basic (explicit Std_Lib::library call) and ChaiScript (library options via constructor parameter) usage. Requested by @lefticus in PR #642 review.
