Make Posts::get() use the built-in method for unset option defaulting instead of the trinity operator to make the code more readable.
Add presets for all default pages that display posts. Allow presets to build on presets. Get rid of all default parameters coded into Posts::get().
Make all the default pages that display posts use the new presets.
Add a preset for the admin manage posts page. Use it. The limit does not work (yet) because of the timeline Javascript.
Add order_by to the Latest Entries dash block as we no longer have that as default in Posts::get().
Fix the loop for handling preset fallbacks so it passes the preset name to the filter correctly.
Prevent circular reference loops bad presets could cause. Keep presets in paramarray.
