[Proposal] Ship a portable ruby runtime instead of Pretzel

[shiftkey]

Rather than try and implement more and more features of Jekyll and Liquid, why not explore if you could include a portable ruby environment (sandboxed inside the package) which then takes care of the jekyll --auto development experience?

Benefits

• compatibility with Jekyll and Liquid
• leverage the existing ecosystem of plugins
• development environment will be equivalent to gh-pages/Heroku
• better cross-platform support (no need for Mono or Win32)
• one language for extensibility (better out-of-the-box experience)

Costs

• does not address dependency on Powershell
• would need to know Ruby if you wanted to contribute extensions
• update all the things

TODO:

• demonstrate how init.ps1 would need to change
• demonstrate how to ship gems inside sandbox environment
• demonstrate how to update Start-Preview script to suit
