... and const versions of three member functions, each returning const_iterator:
* Plist::Dictionary::Begin()
* PList::Dictionary::End()
* PList::Dictionary::Find()

Bug: when creating a new Dictionary object (for example through PList::Node::FromPlist(plist_t node) ), the dictionary_fill function is called from Dictionary() constructor in line 50. It seems that the intended way of calling dictionary_fill() is to pass the _map object by reference, however it is actually passed by value. Thus the changes to the map object made by dictionary_fill() are discarded when the function returns.
Fix: pass _map by reference to keep the changes

While iterating over all the keys stored in the source Dictionary
to copy them to create the copied Dictonary, the name of the key
being copied was only set to a non-NULL value for the first key
we copy. This was then leading to an assertion when trying to
create a std::string from a NULL pointer. Simple test-case:
int main()
{
PList::Dictionary a;
PList::String b("Hello");
PList::String c("Hi!");
PList::Dictionary d;
a.Insert("Key", &b);
a.Insert("Another Key", &c);
std::cout << a.ToXml() << std::endl;
d.Insert("dictionary", &a); //CRAAAAAAAAASH!
std::cout << d.ToXml() << std::endl;
return 0;
}
