Provide an interface to read the titles of the running processes on Windows

[dvarrazzo]

Originally submitted by daniele.varrazzo as issue 6:

I only know it can be done (see Process Explorer [1]), but how, I don't know.

Also, I wouldn't know if it should be a graphical interface (displaying
processes in a tree, allowing to send them signal etc.) or a command line
tool. I suppose the first would be more useful from a windows user PoV but
more complex to write and with fat dependencies.

Contributions are welcome.

Comment by daniele.varrazzo:

Sysinternals' "handle" program [1] returns the value as well

but the source file (that must be no more than a couple of syscalls) is not available anymore [2].

You could try modify the buffer returned by GetCommandLineA and GetCommandLineW.
Doing so can't change process name, but can change process command line. And it's visible in Task Manager and Process Explorer.
