Add MinHook-based overlay for Windows x64.

This commit adds MinHook as a 3rd party
dependency and adds an alternative HardHook
implementation that makes use of MinHook.

This new MinHook-based HardHook implementation
allows us to provide an overlay for Mumble on
Windows x64.

The x64 overlay hasn't seen much testing in
real-world x64 games, except some minor testing
for World of Warcraft running in x64 mode, where
it works just fine.

There seems to be a compatibility with the Uplay
overlay, which causes Far Cry 4 to crash at the
"Press any key to continue" screen that is shown
just after launching the game. However,
Assassin's Creed: Unity works fine, so it might
just be a Far Cry 4 issue.

The x64 overlay also seems to interoperate with
the Steam overlay just fine.

I think this is a good starting point for the
feature. Let us get it into snapshots and let
us try to squash any addition bugs we find.
