[boost] [property_tree] Two pull requests removing rtti and exception dependencies

Hi, I have two pull requests against property tree that I haven't heard anything about.. The first replaces usage of typeid(Type).name() in exception messages with boost::typeindex::type_id<Type>().pretty_name(). The second uses macros from no_exception_support.hpp to replace try catch blocks. I was hoping these might get into 1.61 so I don't need to carry local changes for too long -- is there any chance of that?
