Patch from ArchLinux. Closes #65.

For now rates won't be colored gray when zero; I'll think about that.

(Patch by Dawid Gajownik)

On my machine, this gives a ~20% improvement in htop process time use with the default config.

Changes in object model: separate class objects to store vtable. Also, nicer UTF-8 display of big numbers.

(for details see https://sourceforge.net/mailarchive/forum.php?thread_name=CAJpkDYeZpwqcWxZ77wq6bMrnhn-KzkU1xAqb3cU0drfnA3n9FQ%40mail.gmail.com&forum_name=htop-general )

* Performance improvements
* Support for splitting CPU meters into two or four columns
  (thanks to Wim Heirman)
* Switch from PLPA, which is now deprecated, to HWLOC.
* Bring back support for native Linux sched_setaffinity,
  so we don't have to use HWLOC where we don't need to.
* Support for typing in user names and column fields in selection panels.

(thanks to Bin Guo)
