[Paredit/Editor] paredit.deleteBackward sets cursor position wrong when deleting a line.

This behavior is a bit hard to describe: if the paredit in the editor is set to strict mode - [λ] - the backspace key executes the paredit.deleteBackward command. If the delete operation deletes a new line (deletes the line in the editor) the cursor position is set 1 character left from what it was before. The leads to a behavior like this if the user does not pay attention:

Wow!

This should be fixed by us swapping out paredit.js for our own Paredit implementation. I have tried filing issues on paredit.js and there is no response.

I just quickly fixed it because this issue is very ugly I think. Changing the paredit implementation is a bit of a bigger task, isn't it? But it should definitely be done soon.

Could be big. Could be small. 😄 I am starting to think it will not be very hard, now that we are starting to understand the token cursor and our own paredit module a bit. We will find out.
