* switch application flag between `hr_timesheet_sheet` and `hr_timesheet`
* renamed `hr_timesheet` application name from "time tracking" to "timesheets"
* move the icon from `hr_timesheet_sheet` to `hr_timesheet`
* removed unused icon from `hr_timesheet`
* renamed `hr_timesheet_sheet` application name from "timesheets" to "timesheets / attendances"
Goal: Display the timesheet icon on the app switcher even if
hr_timesheet_sheet is not installed to be able to acces the Activities
without the full timesheet integration.
- Hide account_id field and add a required project_id field on timesheet entries
- Remove is_timesheet field: as project_id is only required for timesheet entries and not for other analytic lines, it can be used to determine wether a line is a timeheet entry or not.
- Remove project_timesheet module as all its functionalities are moved to hr_timesheet
- Replace timesheets on contract option on products by timesheets on project
- Small fixes and improvements in timesheets and projects views and groups
