sysutils/mxkill: initial import of package

MXkill is a user friendly X/Motif graphical user interface to the ps
command.

Features:

* All ps command options, including pipe,  can be used to
  filter the ps output.
* The ps output is displayed in a scrolled list window.
  The vertical or horizontal scrollbar will be active if the
  output goes beyond the viewing area.
* One or more processes can be selected interactively by mouse, and
  standard Unix regular expression syntax can be used to select
  processes as well.
* Signals can be chosen from the menu in order to be sent
  to the process/es. By default, the signal is 9 (sure kill).
