title: Unity3D and Soomla, error in PostBuild processing
body: <p>I'm trying to make build for iOS in Unity5. In my project I have Soomla plugin. And when build done, in console I can see error message.
  That message says that there are problems in 31 line of Soomla_CoreRunner.py file and in 32 line of Soomla_StoreRunner.py file.
  That lines have same line of code</p>
  
  <pre><code>pbx_object = XcodeProject.Load(pbx_file_path)
  </code></pre>
  
  <p>It seems like pbx_file_path is wrong. Here is how pbx_file_path is built</p>
  
  <pre><code>pbx_file_path = sys.argv[1] + '/Unity-iPhone.xcodeproj/project.pbxproj'
  </code></pre>
  
  <p>So how to fix it? Why it gives error?</p>
