When going to the General Settings and clicking a link generating
breadcrumbs, the breadcrumbs would not always read "General Settings".
Not sure why, but Odoo seems to takes the breadcrumb name from the last
ir.actions.act_window with the res_model being "base.config.settings".
In google_calendar: such an action was named API Configuration.
In hr_attendance: the settings wrongly inherits from base.config.settings
without renaming the model.
-> Model is renamed to attendance.config.settings like
in other modules (e.g.: sale) to avoid collision.
