Changed the escaping system - theme_format_expand_data()'s

Browse source 
EXPAND_FLAG_IGNORE_EMPTY now also checks if the argument is a $variable that
is empty. Statusbar now first expands the formats and after then expands
$variables. Should fix at least when trying to print #$$$ channel in
statusbar.
