Add timelet details box.
Use two pane layout only on wide screen displays.
Use em instead of pixel size if possible.
Split up SASS files.
Design details box.
Use entire line to expand/collapse a timelet.
Add close and save buttons to timelet details box.
Use solid line when editing a contentEditable field.
Save and validate timelet values inline.
Rename expand/collapse method to avoid name collission with Marionette.
DRY.
Don't render the entrire collection again on sync but just on create.

This way the collection is rendered on on initial page load and saving a
model will not result in the re-rendering of the entire list.
Typo--.
Refactor strict setter to gloabel model class.
Use normal object for non-persistant timelet status attributes.
Reflect inline editing changes in feature specs.
Store the expanded state in the view instead of the model.
Control the mouse pointer shape on the entire page.
Update no-timelets text.
Remove the option to edit or create a timelet with the clock view.
