Merge master: the shortcut table, local models, and a Mac still in them

Four files disagreed, and all four the same way: master had turned things the
Mac branch wrote out by hand into one list to read from.

Shortcuts are the whole of it. master gave every binding a row in
hotkey.SHORTCUTS, so the Mac's DESKTOP_IDS is gone and CarbonHotkey reads the
desktop id off that row, which also gives the new cancel key a status line on a
Mac. Settings builds its four rows through master's _shortcut_row, and that one
now asks _install_buttons for Install and Remove, so macOS gets a combination
box and nothing to press, and everywhere else the button says the desktop's own
name. dikte.py starts the listener from the same table, on macOS whatever the
setting says: there is nothing installed for it to be a fallback to.

The rest is two imports and a paste list that lives in paste.Desktop now.
