0.6.0.0

This release marks a new life for this tool. Main changes:

• Rename spacchetti-cli → spago (#23)
• Publish on NPM under the new name purescript-spago (#35)
• Add some commands from psc-package:
  • init (#12): initialize a new sample project with a spago.dhall and a packages.dhall config files
  • install (#11, #32): concurrently fetch dependencies declared in spago.dhall file
  • sources (#13): print source globs
  • build: compile the project with purs
• Migrate old commands from spacchetti-cli that are specific to local psc-package projects:
  • local-setup is now psc-package-local-setup
  • insdhall is now psc-package-insdhall
  • clean is now psc-package-clean
• Add some commands from purp (#26):
  • test: compile and run a module from the test/ folder
  • bundle: bundle all sources in a single file
  • make-module: export the above bundle so it can be required from js
• Stop depending on dhall and dhall-to-json commands and instead depend on dhall and dhall-json libraries
• Freeze spacchetti package-set import in packages.dhall, so dhall caching works for subsequent executions
• Move to v4.0.0 of dhall
• Add integration tests for most of the commands (#31, #30)
