Refactor start scripts, Fixes #7 #8 #9 #10

[ronilaukkarinen]

Project start scripts have been refactored completely.

Changes:

• Deprecated docker and vagrant - they are horribly outdated and we can't support them no longer. dudestack-docker has been retired.
• Add working WSL support (documentation), linked also to windows-lemp-setup
• Modularize bash scripts, add files as partials. From now on we need to edit files under bin/tasks and no need to touch main files macos.sh and wsl.sh
• Beautiful formatting and instructions to start script
• Prevent running directly with bash or sh to prevent possible issues with them
• Variable all the things - no need to search and replace stuff
• Fix typos
• Fix WP-CLI commands, there were couple of issues with it
• Fix cleanups - we had wp-cli.yml credentials left saved to project - oops!
• Add some checks (is git found, are certs created, is mkcert found etc.)
• Add extra notifications that these scripts need dudestack and dev servers to work
• Move everything to .env_createproject in $HOME. No more setup.sh or complicated generate scripts, everything should work directly from dudestack repo WITH updates in the future

Made it even better, now it recgnized where you run the script and can point the imports even they are not in correct location. Btw this PR Fixes issues #7 #8 #9 #10.

Tested by me just now on macOS:

Tested by @divn just now on WSL (Ubuntu 18.04 built on windows-lemp).
