Install Louie for Python3

I needed Louie for a Python3 script, but it is not available through apt-get. To install directly from the github, just use the following command which makes use of pip3.

pi@raspberrypi:~ $ sudo pip3 install git+git://github.com/11craft/louie.git

In order to check for the installed modules in your python3 installation:

>>> import pip
>>> installed_packages = pip.get_installed_distributions()
>>> installed_packages_list = sorted(["%s==%s" % (i.key, i.version)
...      for i in installed_packages])
>>> print(installed_packages_list)
