To help with storing strings within tables, I've replaced the unused '_padding' member of 'Toy_String' with 'cachedHash', which is set to zero on string allocation. The hash of a string isn't generated and stored until it's actually needed, as the rope pattern means not every string needs a hash - hopefully this will save unnecessarily wasted time. When a hash of a string is needed, the hashing function first checks to see if that string already has one, and if so, returns it. Again, less time wasted. When generating a new string hash, the hashing function takes the string's type into account, as node-based strings first need their contents assembled into a simple char buffer. Other changes include: * Changed 'TOY_VALUE_TO_*' to 'TOY_VALUE_FROM_*' * Changed 'TOY_VALUE_IS_EQUAL' to 'TOY_VALUES_ARE_EQUAL' * Added a missing '#pragma once' to 'toy_print.h'
