add proper links to the latest version of each page to the head

This maps the current articles to new new articles whenever possible.

Unfortunately I couldn't find the right mapping for the following resources, they either don't exist (yet) in the new IA or I missed them:

Not moved:

• /videos
• /tips-and-tricks (created a mapping, but we need to port these over)
• /extensions-gallery
• /contributing
• /clean-testing-environment

  Unsure:

• /blackboxing
• /settings
• /rendering-settings
• /heap-profiling-summary
• /heap-profiling-dominators
• /heap-profiling-dom-leaks
• /heap-profiling-containment
• /heap-profiling-comparison
• /authoring-development-workflow

@Meggin, when you're back, could you take a look? For now, let's merge the ones we have.

Nice. thanks!

Can you file a ticket to address the missing/incomplete items? Don't want to lose those.

Good idea, will do.
