Makes type conversions explicit, if they alter a value

When comparing the type, it has to be masked with 0xFF because of
cJSON_IsConst and cJSON_IsReference.

NOTE: This can change the assembly slightly, in my case it reordered two
instructions. This is due to the change from:

    which = (10 * which) + *pointer++ - '0';

to

    which = (10 * which) + (*pointer++ - '0');

This means that after the change, the subtraction runs before the
addition instead of after that. That shouldn't change the behavior
though.

This expression was always false.

cost for sorted objects to O(N)

It's a bit of a shame to use the sorts, because cJSON is otherwise incredibly stable (json->cJSON->json is unmodified modulo formatting),
but it means we get usable performance, rather than O(N^2) which will make CPUs cry.

Correct comment and variable declaration style to be more compatible. Added cJSONUtils_SortObject for sorting the members of an object alphabetically.

Also add a new #define to cJSON.h for SetNumberValue.

start of JSON Patch implementation. cJSON gained a cJSON_InsertItemToArray which pushes elements up by one.
This is needed for JSON Patch. Everything but Test is implemented for ApplyPatches.
