Inspired by what is done in the task kanban of the project module,
add examples of kanban stage setups for UTM campaigns, and allow users
to load them.
There have also been some minor changes to the campaigns view:
- The helper message when there are no UTM campaigns has been changed
to a more descriptive message.
- All stages that existed by default (hardcoded in the data XML) have
been removed except default New one. An user with a fresh database will
have no stages in their kanban. The old hardcoded stages have been moved
to the demo data instead, so they will still be added by default if the
user installs demo data.
- The ghost columns that appear in the kanban when no stages exist have
been renamed to match the old stages that were hardcoded.
- When the user opens the view to create a column, the 'See examples'
link will appear below the 'Column title', just like in the project
addon, and clicking it will open some examples specifically made for UTM
campaigns. Clicking on the 'Use This For My Kanban' button will load the
stages of the selected example.
- A min-height property has been given to the example modal view so that
the view does not change size depending on the number of rows in the
ghost columns.
