firstboot: dont show normal mainmenu in help pages
Created by: fonfon
When firstboot is not finished, do not show the normal mainmenu in the help pages. Instead, only show two links: the help page itself and a link back to "FreedomBox Setup".
- templates: renamed
add_nav_and_login
tomainmenu_right
- templates: introduced block
mainmenu_left
to be able to overwrite it - some minor adaptions like removing an orphaned link, adapting titles and using cfg.box_name.
I defined the variable firstboot_finished
two times in
https://github.com/fonfon/Plinth/blob/first-boot-improvements/plinth/modules/help/templates/help_base.html because django doesn't assign variables outside of block
statements, and block
statements can't be inside of if
clauses.
