* added tap version checking logics. Many tap32 versions are broken,

Only version 9.8 and later support IPv6, 9.8 is broken with IPv4. Thus,
we are using the same minium version as openvpn 2.3: tap32-9.9

* created our TAP/TUN handle-object (equivalent to the *nix init_tun() 
function), this still requires some more logics to be
complete.

* added logics to set the tun up (+a fixed sleep, to wait for it to
come up)

* we now also store the device's GUID, as we need it for creating the
handle.

* added the exports of tap32: src/include/tap_windows.h , for the sake 
of upgradability. This file contains version-specific defines for the 
driver.

* happy new year!
