iUSB Tunnel 1.2.0

iUSB Tunnel 1.2.0So yeah I made this program some time ago but only used myself and didn't release it, anyway yesterday I added support for tethering redid the design some, added help buttons under each category and added a about button so I decided that I could just as well release it since there might be someone who would actually use it. If you like it feel free to spread it as much you want
