top: optional wider non-scalable cols

This commit accommodates those fields which may have
suffered truncation due to these default limits:
  . 5 digits for uid/gid type fields
  . 8 characters for user/group type fields

With a new interactive command, users can increase the
width of all such fields, or return to the defaults.

Note:
   There are no restrictions on the amount added to
   the defaults.  The user is free to vastly exceed
   screen limits which simply means such fields can
   never be displayed.
