Release postponed by a day:

* Fixed all warnings obtained in Visual Studio 2005 and 2010
* Reverted SFINAE in CTOR for vector to separate overloads for vector_range and vector_slice (does not work with VS 2005)
* Moved default-implementation for predicates to forwards.h, otherwise Visual Studio does not recognize forward definitions properly
* Removed unnecessary Boost.filesystem and Boost.system components check from dist-package
* Adjusted version number in Doxyfile and CMakeLists.txt
