Hi Everyone,

As discussed in #443, I'd like to start discussing shelljs@1.0.0 features on a high level.

v1.0.0 features [@shelljs/contributors, feel free to edit]:

• Async versions of all commands (Syncify with a Subprocess. #402, feat(async): all commands have async versions #387)
• Plugin System (Plugin System. #391)
  • It would be quite nice to impliment all built in commands as plugins.
• Code Style Guidelines (chore: switch from JSHint to ESLint #317)
• Miscellaneous cleanup/refactor of everything.
• Maybe a logo? (I know @nfischer was working on this.)
• Linting & style checking
• Switch testing to mocha (which helps with code coverage)
• Test coverage (95+% before hitting v1.0.0)

Thoughts?
