dealing with disappearing edit boxes

addresses #8 in the header settings (form_name, description)
closes #8
if no list exists, add a button to create a new list

fixes #6. (do we want this button to always be available, rather than in
the dropdown?)
moved edit list into row view

this will make it easier to try #7
list edit box is now position:static

this prevents the buttons from becoming unclickable when they drift into
the next row. closes #7
