feat(Net): add IPIP DATX support.

WinMTR (Redux) v1.0

-------------------
+ added IPv6 support
- removed Windows 2000 support (kind of... can be added again with ease I guess)
+ hop information / properties can still be viewed if state is "stopped" or "stopping"
* added start delay of about 30ms before starting to ping next hop (should improve performance)
! fixed trace/hop list freeze (one of them being the use of _beginthread and not _beginthreadex and waiting for it's handles...)
* theme support (now uses OS's default theme instead of Win98
! other minor or critical fixes (such as leaks)
