dither for Windows 0.1.0.24

Deletion history for Pages and Quick Notes, scratchpads can show completed to-dos, and custom sections reorder by dragging from Home.

Also fixes: expanded to-do rows showing the wrong section, a checkbox that would not uncheck a completed to-do, custom section icons ignoring their colour, and the background texture toggle reverting to stripes.

Install over the top of any earlier version; your data stays put. If Windows shows "Windows protected your PC", click More info > Run anyway (the installer is not yet code-signed).
