introduce represent_datetime

settings helper that turns a given datetime obj into a unicode string representation according to locale and user settings:
1) look if a fixed 'timestamp_format' is given in the config
2) check if a 'timestamp_format' hook is defined
3) use :function:`pretty_datetime` as fallback

This introduces a new hook 'timestamp_format' that accepts a datetime
as only argument and returns a string
