Another round of fixes:

Browse Source 
. Replace my NIH-suffering code to detect the number of lines on
  the terminal by the curses variable LINES.

. Fix the selection code for countries with more than one screenful
  of locations.  The very few people living in America/US/Pacific
  now won't be charged for Indiana any longer... :)

. Removed the gross code that copied over the timezone file to
  /etc/localtime, and create a symlink now instead.
