Word count plugin

[msamsel]

MVP

The plugin should provide information about the number of characters and words in the editor.

1. Expose a word counter container with automatically updated content. Display it as Characters: NNN

   Example:

   .create( container, {
     wordCount: {
       container: myContainer
     }
   } )
   .then( editor => {
     myContainer.appendChild( editor.plugins.get( 'WordCount' ).wordCountContainer )
   } )

2. Support counting words and characters. Display it as Words: NNN. Characters: NNN. Provide configuration option to disable/enable given field:

   • config.wordCount.displayCharacters
   • config.wordCount.displayWords

3. Allow on output customization. There should be a render function which allows on an update of any element you want config.wordCount.onUpdate( stats )

Next steps

1. Support limits for words and/or characters config.wordCount.wordLimit/characterLimit (package.json should be indented with tabs #7):
   • Indicate the limit by changing the style of the WordCounter container
   • display limit as: Characters: NNN/MMM
2. Highlight the words/characters above the limit in the editor (similar to Twitter) (A builder's option to create non-AMD and AMD-without-polluting packages #8).
3. Display progressbar (Introduce promises lib #9).
4. Improve internationalization (Plugins path resolution #4).

Can you move the things from "next steps" to new tickets?

I create tasks for it and make reference to them in this issue description.
