Refactor editor cont.

[Yukaii]

Changes

• Seperate line:column and selection event binding
• Implement multiple event listener on the same CM event

  const editor = new Editor()
  editor.on('cm-event', function() { console.log('first function 1') })
  editor.on('cm-event', function() { console.log('first function 2') })

  • Editor class maintain an array of functions internally, call each one on CM event sequentially
• Move addStatusbar method into editor class, since it's component of editor
• Drop global ui referencing in extra.js
• Minor coding fixes
• Create a editor config class (public/js/lib/editor/config.js), just a simple object store that can be shared across classes.

  const config = require('./lib/editor/config')
  config.abc = 'xyz'
