[Boost-build] BBv2 msvc.jam: An attempt to reduce code duplication in actions

I tried to reduce code duplications in actions in msvc.jam (see the attachment).

I coudn't find much documentation on "on" rule and target-specific
variables, so I'm not sure that my code really does what I think it
does.

If you think my idea is good, I'll change the rest of the actions this way.

Also, can someone explain me the magic behind the following:

@"@($(<[1]:W).rsp:E=$(nl)"$(>)" $(CC_RSPLINE))"

So I'll be able to perform better code reduction than I did in my
patch. Is @()  a special operator to create files?
