[MERGE] [IMP] 'Stage Bar Manu' Task. This task improves the statusbar widget. Folded columns are 
not hidden anymore, but available in a side menu accessible after other stages. The 
purpose is to be able to have access to all stages using this widget. This way we will be 
able to remove some action buttons in form views in a future task.

This addons branch updates the stages domain for leads, claims, applicants, tasks and 
issues.
[FIX]crm: mark as lost use now case_cancel instead of case_mark_lost because stage of lead were set to lost instead of dead
