RPG demystification, cont'd
Revert b4ff7d4 b20a3b7 . Temporarily remove
todo-filter. This brings back the big performance issue of always
displaying completed-todos, but fixes #2180 #2189. See #2180 for
discussion.

checklists WIP
Tasks: add double-click to edit, and date-picker-popup for
due-dates. Show red dates when overdue (basic)
checklists: checklist as <li> instead of <label>, so that inline-editing
doesn't trigger checkmark. Unfortunately means we need to replicate some
bootstrap css
checklists: tmp commit to showcase how inline checklists look on
tasks (only for todos for comparison)
checklists: add inline-checklists user preference, and hide inlines when
editing
fix #2184 put dbl-click for task._editing on the correct element
checklists: better handling of saveTask, keypress:13, and remove-blur
checklists: handle backspacing an empty CL item
