title: Pabot - Unable to run parallel robotframework tests
body: <p>So, I'm working on a robotframework test project, and the goal is to run several test suites in parallel. For this purpose, pabot was chosen as the solution. I am trying to implement it, but with little success.</p>
  
  <p>My issue is: after installing Pabot (which, I might say, I did by cloning the project and running  "setup.py  install", instead of using pip, since the corporate proxy I'm behind has proven an obstacle I can't overcome), I created a new directory in the project tree, moved some suites there, and ran:</p>
  
  <p><strong>pabot --processes 2 --outputdir pabot_results Login*.robot</strong></p>
  
  <p>Doing so results in the following error message:</p>

  ValueError: Attempted relative import in non-package</p>
  
  <p>Apparently, this has to do with something from the runner.py script, which, if I'm not mistaken, came with the installation of robotframework. Since manually modifying that script does not seem to me the optimal solution, my question is, what am I missing here? Did I forget to do anything while setting this up? Or is this an issue of compatibility between versions? </p>
  
  <p>This project is using Maven as the tool to manage dependencies. The version I am running is 3.5.4. I am using a <strong>Windows 10, 64bit</strong> system; I have <strong>Python 2.7.14</strong>, and <strong>Robot Framework 3.1a2.dev1</strong>. The <strong>Pabot</strong> version is <strong>0.44</strong>. Obviously, I added C:\Python27 and C:\Python27\Scripts to the PATH environment variable.</p>
  
  <p>Edit: I am also using robotframework-maven-plugin version 1.4.0.8, if that happens to be relevant.
  Edit 2: added the error messages in text format.</p>
