Added project window
Add support for PyQt5

use can choose the qt api to use by passing the --qt command line options.

E.g.:

- to run with PyQt4: ``QIdle --qt 4``
- to run with PyQt4: ``QIdle --qt 5``
Add a bootstrap script that warn about missing packages
Fix a bug with embed_packages_into_zip when running with python2

the function was acutally copying *.pyc files. It is very important for namespace package to have a real __init__.py as the root file.

This should help @jmwright with pyQode/pyQode#16
