v2.9.0

• extract list of packages and ask to open installation manifest in editor or not (relates to #63), same thing for the configuration file
• Removing some packages from the default installation to conserve space:
  • Removing cltl-vu-python from the default packages (the folia-naf converter is not really in use nor maintained well nowadays and the git repo comes with some big files that take up too much space)
  • exclude xgboost from the default installation as it takes up a lot of space and is not a direct dependency
• add extra user input stage with updated instruction prior to ansible start. This ensures people know to expect a lot of output they can ignore and a long wait whilst things are installing, and so understand what to do when ansible asks for the BECOME password (addressed an issue raised by @pboot)
• fix for failure to start nginx #151
• adapting the strict python check and making the bootstrap also work when python 2 is absent in some cases
• ensured ~/bin is in $PATH immediately after bootstrap
• added more feedback to lamachine-start-webserver script
• implemented CSV export ability for lamachine-list
• do linux distribution detection and warn users if they run on an unsupported or outdated platform
• [documentation] updated FAQ
