v1.2.0

• Allow usage of grunt plugins that are located in any location that
  is visible to Node.js and NPM, instead of node_modules directly
  inside package that have a dev dependency to these plugins.
  (PR: #1677)
• Removed coffeescript from dependencies. To ease transition, if
  coffeescript is still around, Grunt will attempt to load it.
  If it is not, and the user loads a CoffeeScript file,
  Grunt will print a useful error indicating that the
  coffeescript package should be installed as a dev dependency.
  This is considerably more user-friendly than dropping the require entirely,
  but doing so is feasible with the latest grunt-cli as users
  may simply use grunt --require coffeescript/register.
  (PR: #1675)
• Exposes Grunt Option keys for ease of use.
  (PR: #1570)
• Avoiding infinite loop on very long command names.
