top: refactor and enhance column width management

Browse Source 
This commit accomplishes the following objectives:
 * remove extra task_show parm added with 'Locate'
 * avoid column overflow with subsequent misalignment
 * eliminate spaces for column heading padding
 * decouple column headings from column data formats
 * eliminate all hardcoded column format specifiers
 * generalize the inter-column spacing management
 * remove Fieldstab.desc in favor of direct nls access
 * set the stage for nls support of column headings
 * set the stage for dynamic changes to justification
