[!!!][FEATURE] New flat post hierarchy and paginated posts index

This changes the blog from the per-year-month-day structure to a flat
structure. A rudimentary migrate command is part of this change set
which does most of the migration from the old to the new structure.

The PostController now supports pagination for posts using the
new TYPO3CR Paginate widget.
[FEATURE] Flag removed posts when in workspace mode
[FEATURE] A (still rough) implementation of endless scrolling
