title: Moving django apps into subfolder and url.py error
body: <p>I have a question about putting django apps into "apps" subdirectory. I have the app called “faktura” in a project_root. I didn’t like the fact it lies there and I want to store all my apps under “apps” subdirectory. </p>
  
  <p>So, I found out that I could extend python path to “apps” subdir, so after looking in the internet, I added this string to settings.py: sys.path.insert(0, os.path.join(PROJECT_PATH, "apps")). Then I added the app to INSTALLED_APPS like “faktura”. Everything worked smooth until I added url(r'^faktura/', include('faktura.urls')) to urls.py in the root. Since that, Django throws the error message “No module named faktura” full taceback is here: <a href="http://dpaste.com/737380/" rel="noreferrer">http://dpaste.com/737380/</a> </p>
  
  <p>What can be wrong here, why only urls.py can’t find the app? And does it can’t find this app if I added it to the PATH? I spent a morning trying to figure out what’s wrong and now I need your help.</p>
