Zero-width space to avoid empty annotation cursoring bug

Browse source 
Add zero-width space to make span-like tags non-empty, so that the browser won't
merge their cursoring positions with the following character.

ve.ce.MWNumberedExternalLinkNode:
* Insert U+200B ZERO WIDTH SPACE inside span (before 'a' tag).
