coordinate_matrix broken on MSVC10

[Thomas Klimpel]

The swap functions of "index_pair" and "index_triple" in "ublas/storage.hpp" take their argument by value instead of by reference. This is most probably a simple typo.

It doesn't lead to problems on other compilers, because either ADL is not used at all to find custom swap functions in std::sort, or iter_swap is found. MSVC10 seems to be the only compiler (std library) that misses iter_swap, but finds the broken custom swap function.

(In [60156]) see #3968: added testcase to reproduce problem

test/sparse_view_test.cpp: test case implementation

test/Jamfile.v2: added target for test run

(In [60215]) see #3968 : add missing file in yesterdays commit

test/test_coordinate_matrix_sort.cpp: test case for problem related to #3968

note to myself: do not commit after midnight!

(In [60623]) see #3968 test/test_coordinate_matrix_sort.cpp: fixed wrong index in check test/utils.hpp: fixed wrong exit code on failure

(In [60780]) storage.hpp: see #3968, applied patch to use references instead of copies in swap implementations
