No focus indicator for the toolbar button - accessibility

[sarbbottam]

Focus indicator is extremely important to keyboard only users. Currently the default browser focus indicator is suppressed via outline: none at quill/develop/assets/base.styl

Either enable browser default focus indicator or compensate it with custom style. You can read more about focus indicator and its necessity at Keyboard Accessibility and Lost Focus

Steps for Reproduction

1. Visit http://quilljs.com/playground/
2. Press tab to reach the toolbar buttons

Expected behavior:
Any focused element must be visible and identifiable

Actual behavior:
Notice that it is not possible to identify which button is focused.

Platforms:
Chrome latest, Mac latest

Version:
1.0.6
