Adding Accessibility support

[ndbroadbent]

I'm interested in making the Mention, Hashtag, and URL elements accessible. We need this for our automated test suite, which relies on accessibility labels. But it's also just a good thing to provide for people who need it.

I'm not 100% sure how to do it, but I'll try to copy what TTTAttributedLabel is doing.

@polqf, instead of the TTTAttributedLabel approach, would you be interested in doing this via accessibility actions? I figure this could work as follows:

• @-mentions will have action name "Navigate to mentioned user "
• #-hashtags will have action name: "Navigate to hash tag "
• urls will have action name: "Navigate to "
• custom types would probably be: "Navigate to "

and obviously we would add methods for overriding the action names for all the ones listed above. I could probably work on this approach and try to get a PR for this if you think this would be a good approach.
