MetasploitModule#client_matches_browser

Returns true if an exploit for +browser+ (one of the +OperatingSystems+
constants) should be sent for a particilar client.  +client_info+ should
be something returned by +get_client+.

If +client_info+ is nil then get_client failed and we have no
knowledge of this client, so we can't assume anything about their
browser.  If the exploit does not specify a browser target, that
means it it is generic and will work anywhere (or at least be
able to autodetect).  If the currently connected client's ua_name
is nil, then the fingerprinting didn't work for some reason.
Lastly, check to see if the client's browser matches the browser
targetted by this group of exploits. In all of these cases, we
need to send all the exploits in the list.

In contrast, if we have all of that info and it doesn't match, we
don't need to bother sending it.
