Snippets

closes #38

This builds off of #52 and does a little refactoring to make the snippet rendering code re-usable.

A user can define snippets in their config

{
  snippets: {
    Foo: '<div>Foo</div>',
    Bar: '<div>Bar</div>',
    Baz: '<div>Baz</div>'
  }
}

Then when a user presses Ctrl+Space or Cmd+Space something like this will pop up:

Ctrl+Space or Cmd+Space will also show the appropriate suggestion based on context. If used with the hints already up, it will close the hints.

Thanks for the inspiration, we just released snippets support in v0.15.0.
