Extension ext-network continued, "translation" function introduced:

Extension ext-network continued, "translation" function introduced:
- Already added network type handler configuration can now be displayed (shown)
  and changed
- Most advertising networks require "hours" for reload time, but other may
  require different time units, therefore a new entry has been added to table
  'network_types_config' to reflect these differences
- "Translation" function 'translateTimeUnit()' introduced which can "translate"
  time units (like W for weeks) into human-readable
- Function createFancyTime() uses now EL code (see newly introduced function)
- TODOs.txt updated
