Extended Capabilities for HR Holidays (Leaves)

• When calculating the number of leave days take into account the employee's schedule and public holidays
• The 'Need Action' mechanism assumes the HR Manager approves leave requests
• Rename 'Leave Requests' menu item to 'My Leaves' (which is closer to its intent)
• Add a new menu item: All Leave Requests
• New way of entering leaves based on the number of days requested, rather than by specifying a start and end date. You tell it how many days to grant and it calculates the start and end dates based on the employee's schedule.
• Allow a manager to approve the leave requests of subordinates (manager must be immediate superior of employee or manager of employee's department and have leave approval rights)
