Create a new subcategory "design/architecture/time"
and rearrange several pages related to time handling and time codes.
NOTE: starting with this changeset, a ''Link-Farm'' is required for cross-links;
since we don't have an automatic solution for this task yet, I have created
the necessary forwarding pages manually in the website repository.
These pages from the TiddlyWiky feature a complete glossary
of terms relevant for time and timecode handling, plus the
architecural decisions related to this topic
