Add the following new Sandstorm features and fixes:

- All Boards page [so it's possible to go back from subtask board](https://github.com/wekan/wekan/issues/2082)
- Board favorites
- New Sandstorm board first user is Admin and [has IFTTT Rules](https://github.com/wekan/wekan/issues/2125)
  and Standalone Wekan Admin Panel. Probably some Admin Panel features do not work yet. Please keep backup of your grains before testig Admin Panel.
- Linked Cards and Linked Boards.
- Some not needed options like Logout etc have been hidden from top bar right menu.
- [Import board now works. "Board not found" is not problem anymore](https://github.com/wekan/wekan/issues/1430), because you can go to All Boards page to change to imported board.

and removes the following features:

- Remove Welcome Board from Standalone Wekan, [to fix Welcome board not translated](https://github.com/wekan/wekan/issues/1601).
  Sandstorm Wekan does not have Welcome Board.

Thanks to xet7 !
