Fix installation process

This issue is to collect some fix need to make in the installation script.

The target is to make the installation work on Raspbian Stretch (9) and Ubuntu 18.04, and make the process simpler.

Some core idea:

• Try to install the dependency software from the OS repository (via apt) and from Python PyPI (via pip3) first. Only install from source (make) if the previous method fails.

ISSUES To be solved:

• SWIG should be installed from Debian repository.
• libatlas-dev doesn’t exist. Install libatlas-base-dev instead.
• Tizonia default installation script only installs Python 2 packages (from https://dl.bintray.com/tizonia/raspbian), not Py3. Doesn’t have a fix yet!
• The final step in install.sh doesn’t prompt the user to use python3 config_generator.py however, the new format is ‘python3 config_generator.py stt tts hotword wake’
• The 99-com.rules file is of Raspbian. We must not write our rule to it. Write to new file, so that when we uninstall the app, we just delete our file.
• Some Python packages, like snowboy, has to be installed from Git source, just because the version published to PyPI is too old.
• Try to install the dependency software from the OS repository (via apt) and from Python PyPI (via pip3) first. Only install from source (make) if the previous method fails.
