replace jsoncpp with yajl (thanks topfs2)
* topfs2/remove_jsoncpp: (21 commits) Fix. Added explicit typecast to platform int to quench warnings for variant use in jsonrpc [win32] replace jsoncpp with yajl Removed jsoncpp Added pragma and license to IClient.h Removed the dependency of jsoncpp in CVariant Switched to use CVariant instead of jsoncpp values in JSON-RPC Added yajl writer for Variant Added yajl parser for Variant Added c_str and have size of variant work with strings Added check for libyajl to configure Added CVariant::type which returns the type of the current variant (easier than multiple isFoo queries) Switched Variant to use double internally, still accepts floats Added swap method to CVariant Moved to use explicit type in CVariant instead of isFoo Added operator== to CVariant Added array and map iterators to CVariant Added CVariant constructor which takes a string pointer and length Added append to CVariant Added isMember to CVariant Removed debug in CVariant ...
