support cusp::complex in cusp::multiply()

[GoogleCodeExporter]

In particular, the sparse matrix-vector multiplication routines need to support 
cusp::complex [1].

Small fix in coo_flat.h to make it compatible with cusp::complex (ints don't 
get automatically promoted to complex).
The rest of the fix will take longer.

The attached patch adds support for limited operations with volatile complex 
number (basically assignment and +) while hopefully not breaking anything. This 
is enough for the current use of volatile in coo_flat.h and probably most other 
uses of volatile.

Works with floats and doubles and I tried all the tests and examples and they 
seem to run fine.
