Default to the status table output

For smart terminals, default to using the status table, using 1/4 of the
terminal height (with a min of 1 and a max of 10).

This behavior can still be overriden to a specific height with
SOONG_UI_TABLE_HEIGHT, and turned off by setting SOONG_UI_TABLE_HEIGHT
to 0.

Test: m   <adjust terminal height, see it shrink when it gets too short>
Test: SOONG_UI_TABLE_HEIGHT=20 m
Test: SOONG_UI_TABLE_HEIGHT=0 m
