[IMP] hr(_expense,_holidays): modify help message

In Employee / Work information / Responsible: there is a lack of
information on the "help message" The objective is to change text
in the help message by the ones below:

Field "Coach":
  -Employee responsible of this employee.
  -The "coach" has no specific rignts or responsibilities by default.
Field "Time Off":
  -User responsible for approving "time off" of this employee.
  -If empty, the approval is done by any administrators or approvers (determinated in settings/users)
Field "expense":
  -User responsible for approving "Expenses" of this employee.
  -If empty, the approval is done by any administrators or approvers (determinated in settings/users)
