wmtop: patch for process name extraction on Linux 

I received the following patch from Tilmann Hentze <0xcafe@directbox.com>
in an email:

> Hello,
> there are processes, that have space characters in their names, for example
> Firefoxe's "Web Content" process.
> The current sscanf line for Linux would only considers the first part of
> the process name, e.g. "Web" and cut off the rest.
> Attached patch should consider the complete process name between parentheses.

> Further I did not touch the handling of removal of "kdeinit", since
> I am not using KDE and am not sure if the assumptions in the source code
> are still valid.

> Best Regards,
> Tilmann.
