Online Editor: Clear Url Address after loading a shared Page.

[jetrotal]

When you load a Shared Code, the address bar always point to the code at the state it was shared.
Then, when you edit the code and refresh the editor's page, the code comes back to its previous state.

Maybe clearing the Browser's address bar could solve this. Or maybe Creating a snapshots list, with different states of the code whenever the user used CTRL+S
