Fixes
- Saving a pinned group no longer leaves you without a taskbar. Changing a pinned group's icon or name restarts Explorer, so the taskbar shows the new icon. When you edited the group from its panel's pencil or its right-click Edit group, the app closed before Explorer was back, and sometimes it never came back. Now the app waits until the taskbar is back, and it only restarts the process that owns the taskbar.
- Apps picked from the list now take arguments and "Open as administrator". Until now only programs added with Browse… showed them in App options. Desktop apps from the list do too: they start through their own Start menu shortcut, so they keep whatever that shortcut already passes and add your arguments after it. Store apps, web and game links and folders still open through Windows, which allows neither, and the options window says so.
Thanks to @Leo9idas for reporting both (#2).
