  Two string types are used.

-std::string type: by value, has smaller buffer optimization, 
used at startup/logging, and for any dynamic strings with 
unbounded possible values

-immutable string handles: by value. When created it looks up 
into a hash to find or create that string. Two immutable strings 
with the same value, will always use the same pointer(like Lua). 
These are never destroyed, they are intended as handles.
