Add list event clearcut logging (1/3)

- Update logging previous screen when QuickContact is opened.
- Log various list events.
- All actions are logged when finished.
- "Load" action is logged when load is finished and when account
  filter is changed, so as to avoid unnecessary repeated logging.
- Some of the "/*...*/" comments are omitted if the variable
  name is the same as the parameter name.
