Allow users to swap between different views of tasks on a page

[CaAlden]

Currently pages are only visible in what is equivalent to a "Daily Log" view. All tasks are assumed to be relatively undistinguished based on the tasks' date. An overarching improvement will involve introducing a few new layouts for pages, but there's no reason that user created pages shouldn't be allowed to present themselves in a different view mode.

New Views

• Calendar: This may actually be multiple views (Week, Month, Year, Decade?) but essentially it would show user tasks based on the date associated with the tasks. You could, for example, create a Week view such that tasks are grouped on the days.
• Notes: A collection of note "cards" which are rearrange-able and not of any fixed size. Notepad #6 is essentially a sub task of this issue.
• Single Flow: Essentially what all pages currently are. New pages should default to this view.
