Rewrite composite shape vector constructors with iterator ranges
Besides the issue of favoring one container type over others, constness
of the contents causes it to be a different, incompatible type. Iterators
solve this in an elegant way.

Make the check_intersection function non-virtual
Almost all shapes were implementing it with a call to get_intersections,
so might as well make the base class do that. Performance loss is likely
negligible.

Math function usage fixes
Add using declarations and #includes where needed, and clean up some
unnecessary ones. abs() is particularly annoying, as the int version
easily gets into the global namespace and doesn't give a warning if
used with floats or doubles.

Don't qualify potentially overloaded functions with the std namespace
Instead put a using std::func before the call. This makes things work if
the template argument is a user-defined type with these functions defined
in another namespace.

Redesign the Vector interface
The constructors from two and three components are now provided directly
by the Vector template, so Vector2 and Vector3 are no longer needed. In
addition, two- and three-component vectors now have named members.
