tdf#143956 Remove page size of Writer templates 3

This patch concerns "offmisc" templates:
- Businesscard-with-logo:
  - use predefined style names to have them automatically translated
  - use automatic date format according to locale settings
  - update preview
  - remove useless duplicate code and unused styles
  - contributor's name to top to fit in A4 and Letter formats
  - remove 1 empty line in table to fit in Letter format also
  - remove useless stuff in settings.xml file. Keep these fields,
because if certain settings are MISSING, xmlimp will consider the file
in old format (thanks to Justin Luth)
  - reindent xml files
