fix double click or click + keystroke to edit a cell

It seems adding contentEditable on click didn't allow the the contentEditable
behavior to kick in. By just always making editable cells contentEditable, we
get around this problem (just one click required). We also don't have to worry
about hovering away disabling editing (annoying when copying from somewhere with
mouse). Only downside to this approach is that editable cells with links have
two links appear and I must know to choose the lower one when using vimperator.
