[Feature] Create a collaborative online web to share markdown notes among users

[raffaeler]

This is a suggestion, given most of the online editors are quite rudimental.
The idea is to create an environment (sort of gist) where one or more users can publish a document and contribute in the browser powered by the Typora engine.
This could be backed by GitHub and provide a very high visibility to the Typora product.

The 'conflicts' could be managed by mean of the git tools (under the hood, not explicitly shown to the users). If I remember well, the use of git to manage the documents is something under evaluation in the desktop application (which would be very valuable) and could be a single effort for both features.
