The drawer button at the left of the tab bar was removed in #202 because it introduced an FAB with the same functionality.
However, the FABs will not appear while a post form is open, it needs two taps to open the menu, which is inconvenient.
This PR adds an option to show the button in the tab bar as before. If the option is enabled, the button is available regardless of whether the post form is open.
