File description is used like a program name in Windows

It is up for debate whether we should put the application name or the description (like I have done in 3cf2f62) into that field . See also: mxre/winres#43

I think the application name should be used for FileDescription, since that property is what's used as the program name in Task Manager.

Yeah, it's weird when a sentence describing what the program does is inserted in places where you'd expect a name (as in the screenshot above). I should probably fix this and also redo the pictures in the README.md.
