First Useful release

This is the first really useful release. I have been working on xmlliterate (which uses cppxmlobj) and found a lot of things that could be better. Especially when it comes to using STL algorithms with xmlobj_vector_typed.

I spent a lot of time looking at boost_1_31_0, especially boost::iterator_facade to provide real iterators for our objects. We use boost::bind with std::for_each and std::find_if all through the code now including the tests so that the code will look a lot better and more Boost/STL like.

Of course another big thing is that it uses stock boost_1_31_0 (but still with Build v1), without any patches, and all of the code is self contained without needing to download the other packages and create aliases to them (which was a pain).

So if you were remotely interested in this stuff, download the latest, and since I'm actively working on it now, bugs should get fixed.
