[Feature request] Monthly sums; daytype column in weekly overview

[Gerry33]

Hi, and thanks for your work. Highly appreciated !

Some simple requests:

• Monthly sum- up of working hours.

• Expected monthly sum- up of all working days with some adjustable daily work time. without weekend or those days marked as holiday|vacation|non- working- day

   In other words: How much do I have to work this month ?
  

• In overview: add column of day type (normal or (holiday|vacation|,non working day ) to see if daytype is set correctly or not at all.
