solve the stricmp/strcasecmp in a dumb way for good.

I might make cJSON_strcasecmp hookable, depending on what feedback i get.
There are now +NO+ #ifdef/#endif WINDOWS clauses, just neat ANSI C.
Also, this DOES NOT represent an efficiency hit for parsing, since the casecmp code is ONLY used for retrieval of object values, which would be after the parse stage.
