In !332, there was some difficulty with having two accelerators for the
"Synchronize calendars" action, so the Ctrl+R accelerator was left out.
This commit adds the Ctrl+R accelerator to gcal-window.ui by specifying
it before the F5 accelerator. The result is that only F5 is shown as an
accelerator in the overlay menu, but Ctrl+R still works.
Ctrl+R was also added to help-overlay.ui, displayed alongside F5.
Fixes#1052
This refactor combines the functions
gcal_utils_launch_online_accounts_panel and
gcal_utils_launch_datetime_settings_panel into a single function that
takes a panel ID as an argument.
Shortcut is added so that time-related system settings can be easily
accessed. See #1023
The code is largely just a copy-paste of the code that opens the
"Online Accounts…" menu.
Fixes#1023
