Loading a new, blank session

[justkd]

Description

While it's possible to delete all cards except the first, there is no easy way to reset the first card without having to change input fields.

We should add an option to "clear" a focused card. Perhaps this could go in the options menu along with a delete button, and could reset all of the fields to empty. This could be useful in creating a blank card track without reloading the page, and could be convenient for editing in general.
