Duration display, time formatting, UI tweaks.

Client Behaviour (ts.js)
========================

- Created EntryView.getViewModel: translates model data to view data,
  specifically synthesizes the start time and duration from the timestamp.
- Added nextModel option to EntryView, needed for calculating the entry
  duration.
- Created EntryView.formatStart: given the timestamp, return the start time,
  in HH:MM format. Code is written for both 24hr and 12hr format, still need
  to write a selector mechanism. For now, uses 12hr format.
- Created EntryView.formatDuration: Get the duration of the entry based on
  this entry's timestamp and and the next entry's timestamp in a display-able
  form. If nextModel is `null` or `undefined` it is assumed that `model`
  is the most recent model and duration is calculated against the current time.
- Changed EntryView.render to use getViewModel.
- Added 'blur' listeners to the mark and timestamp input fields to close them
  without persisting the changes.
- Created EntryView.update: Refresh the display based on the model using the
  existing DOM elements.
- EntryView.save() now uses EntryView.update() instead of EntryView.render()
  and no longer includes an implicit close()
- EntryView.close() has been split into seperate save() and close() functions,
  to persist the changes and hide the input dialogs, respectively.
- EntryListView.addOne now passes the nextModel to EntryViews is creates.
- EntryListView.createNewEntryOnEnter() now clear the new intry input after
  creating a new entry.
- EntryListView.render() now uses a for-structure to traverse the entry
  collection and passes the nextModel (if there is one) to EntryListView.addOne.

Client UI (ts-screen.scss)
==========================

- Font size, family, and color adjusted on timeline and user input fields.
- Day seperator secondary header colors adjusted.
- Mark column width shortened, timestamp and duration columns widened.
- Styles added for notes UI

Client UI (index.yaws)
======================

- Markup changes needed for getViewModel chanes.
- Expanded day seperator.
