Get rid of the need to manually copy over plugins and includes

[strogonoff]

This (1) adds unnecessary steps and (2) robs theme users of ability to have plugins/includes auto-updated alongside new theme releases.

Options:

• Option 1: Somehow make those steps part of automated gem theme installation

  • Not sure if possible with includes since theme includes seem to get ignored if site uses its own include directory
  • Maybe looking into include_relative again could make it work somehow?
  • Move plugins to their own gems
  • Is it viable to decouple plugins from the theme and publish separately?

• Option 2: Provide a way to set up a new site in fewer steps by bundling a template/skeleton project for this purpose

  • Not great, leaves issue with plugin/include auto-update unsolved

To investigate: the issue with relative includes may be possible to eliminate by adding includes_dir: . to site’s _config.yml, and using the regular non-relative include henceforth.
