Changed <li> display to 'inline'.

It doesn't look too bad and it saves a bit of screen estate.
Fixed form change ignored by IE10.0.

Provided that anyone is unwise enough to use above software, I attached the
handler to 'keypress' because IE10.0 does not pass a pressed enter key as form
change event. Even though it is jQuery!!! JESUS!!111
Fixed lost href focus in IE10.0.

It seems that by clicking the map, the link that had gained focus via
$().focus() loses it instantly. The call works we delay it.
Allowed GeoJSON_clone to be a list of geometry ids.

For simplicity, I used a string rather than an actual array.
Removed unused variable 'documents'.
Fixed UI glitch for multiplicatively attached documents.
