QHostAddress doesn't realise that anything in 127.0.0.0/24 is localhost

Any address in the 127.0.0.0/24 is localhost, but QHostAddress doesn't realise this. That means that code like this:

https://qt.gitorious.org/qt/qtbase/blobs/master/src/network/access/qnetworkaccessbackend.cpp#line374

will incorrectly think the address is remote. This matters because linux distros often set the machines name to 127.0.0.2, for example, my hosts file has:

127.0.0.2 marge.westpoint.ltd.uk marge

as well as the localhost line pointing at 127.0.0.1.
