Allow links to be clickable when editing in Markdown Pro

[danielfernandez]

Many times, when a note is being edited using Markdown Pro, you need to visit one of the links in the document. Having to switch to "Side by Side" or "Preview" for that is a hassle, because there are many notes that are alive enough that you keep in Markdown editing mode 90% of the time.

So it would be great if we could just right click -> Go to URL on links, just like in Google Docs. After all, they already appear in blue so not being able to visit them is even a bit confusing.
