multiple improvements to history look and feel.

 * history.c, scroller.edc (from multiparty-list.edc): use scroller
   theme for genlist similar to multiparty details.

 * history.c: history formats line_id using phone_format() function.

 * history-bg.edc: smaller buttons for "All" and "Missed", with text
   centered (no subtitle).

 * history-bg.edc: lists will go up to the scroller (rel1).

 * history.edc: list items are bigger (120px), allowing more space
   between items. Fixed positioning of time and type parts.
