Remove --gr-autocomplete. Always put border, border-radius, padding
on gr-autocomplete, unless it is classified as "borderless".
Add a border-radius also to the gr-autocomplete-dropdown. Makes it
look nicer.
Adjust the vertical offset of where the dropdown is shown in
gr-autocomplete to 31px, which matches the default styles. Only needs
a different value in gr-account-entry, where no border and no padding
is used.
Drop height:2em from gr-autocomplete usages, which makes it fall back
to height being calculated from border, padding, line-height as usual.
Also drop height:2em from input,select,textarea form styles, and
align their padding to 4px as used everywhere else.
Align also the standard border-radius and padding of input with that
of gr-autocomplete.
