Checking this in to make sure I don't end up creating broken installers
again. I doubt that this is useful for anyone but me - but then, I don't
think anyone but me creates Windows installers.
Background - when Fedora 20 updated the cross-built version of Qt for
Win64 something broke. Subsurfae installed with those DLLs will crash.
Replacing the older 5.3.1 DLLs fixes this for now, so I have a directory
with just those DLLs and simply replace them in the staging directory
before calling makensis.
