[IMP] Improved and added functionality of Hr and Hr related modules

hello,

      i have improved following points

-HR leaves:
    -The grey/green bullet should be in leave summary
    -from the employee form, show only grey lines (grey bullet, green has already been reported) -> filter on "Leaves to be reported)
    -Create a menu entry named "Employee's Leaves" (=leaves requests) filtered on grey bullet (Leaves to be Reported), year, group by employee
    -the manager does not seem to be follower of leaves/allocation

-Departement
    -review subtypes order and rename one of them

-Expenses
    -the warnig "The employee should have a home address" is not necessary anymore
    -add a menu "Expenses" in accounting under supplier this menu open approved expense to generate accounting entries
    -add help near journal view
    -Add menu Expense to Approve under Expenses
   - Added field employee account payable which will be set from home address if exist or will ask to set value before generating accounting entries.
 
Employee
    -Add 'Absence of the month' button in Employee Form

-add needaction to Expense to Approve ,LeaveRequest to approve and allocation request to approve
-timesheet to approve,Expense to Approve,LeaveRequest to Approve,Allocation Request to Approve does not seems to decrease in real time like other need action
-hr officer should be able to see department form view and follow it and check subtypes
