Copyright, attribution, pyinstaller, rename

I felt the existing attribution to Marcan in the source header wasn't enough,
so, I added the link to the original source together with the copyright to the README.

I also added a special thanks to the program output.

For the binary release, I switched from py2exe to pyinstaller (and packed with UPX).
It's much easier to build with pyinstaller, and it creates a single file that does not need VC redist (and it can build for non-Windows, too).

I also renamed the files from reset_tool (which was too generic) to wiipcrt.

Small improvement.

Handle KeyboardInterrupt for a nicer exit when the user presses ^C.

That's all.

Wooooh!

Added a bunch of stuff and improvements.

Try --help for more info.

First! Well, re-release, anyway. ;)

Simply run it and follow the instructions!

If you need help, see the README.txt and follow the website URL.

PS If you get any errors about missing DLLs, try installing vcredist (2008 and 2010).
