Session Traversal Utilities for NAT (STUN) - Client

[WiiLF23]

Just something I pieced together, converted main functions from C++ -> C, and implemented a GUI. I needed a easy testing client for NAT traversal work. This just made sense.

For those who would like to use it.

it's just size_t / sizeof issue in C macro ?
struct size is less than DWORD max.
