We usually prefer local variables over instance variables in partials.
This way we'll be able to call the partial from views or components
where the instance variable isn't available.
And since we're using the `path` variable to configure the URL, we don't
have to specify extra variables like `@budget` or the namespace `:admin`
in `form_for`, since Rails only uses those variables to set the URL.
Show information about longitude and latitude in a budget heading
Show information about custom content in a budget heading
Fix render of map (zoom scrollable and points clickable)
Fix typo in app/models/map_location.rb
To make it more consistent with the rest of the Admin panel,
the CRUD for budget groups and headings has been changed
from the old "all-in-one" form to a separate form for each resource.
