make signs_able to display the interact_keyword setting

Browse Source 
as used by CWz's mod of the same name

Write @KEYWORD (all caps, with the 'at') into the sign's text to display
the keyword.  Keyword displayed is automatically updated if the 15-second
update interval detects that it differs from the minetest.conf setting.

The keyword setting is only read at startup.
