* Tweaks help_text to indicate that travel assistance is to Sydney
* Includes the required migration
This migration doesn't change the DB so it's safe to apply with the system live.
It's really annoying when you are adding a proposal and you hit tab and
end up on the link to the Hack website. There's no need for this and at
least on newer browsers we can pretty easily skip the links for tab.
Unfortunately because this is model text it generates migrations. As we
know these migrations don't actually do anything, so they are annoying
but not actually harmful.
Link to the T&C and Code of conducts so people know what they are
accepting. Create this as a static link because i don't know how django
would accept this being something dynamic on the model.
This annoyingly creates a migration, but it's not a real change and
easier to accept it now than fight django forever.
