[boost] function<>::contains

I added a test case to bind that tests bind objects with function<> and 
function<>::contains; function<> doesn't have such test cases. In the 
process I patched the implementation of function<>::contains to work on MSVC 
6.

However contains_test.cpp will still fail on MSVC 6, because it's misnamed: 
it mainly tests target() and operator== and I didn't attempt to fix these.

I added contains2_test.cpp to the function<> test suite that only tests 
contains(). It should now pass on MSVC 6.
