Check_MK Werk 1489: Added iCalendar import for generating timeperiods e.g. for holidays

ID: 1489 Title: Added iCalendar import for generating timeperiods e.g. for holidays Component: WATO Level: 2 Class: New Feature Version: 1.2.5i7 The timeperiod management module of WATO has been extended with an import mode vor iCalendar (*.ics) files. This can be used to easily create timeperiods for holidays which then can be used to exclude them from your other timeperiods. There are a lot of pages on the internet which provide you with iCalendar including the appointments for either the holidays of specific years. They might also contain appointments which have a recurrence configured, e.g. on a yearly base. The import currently deals with monthly and yearly recurrences of appointments by resolving them for the configured time horizon. After interpreting the iCalendar file, you will be redirected to the timeperiod creation dialog where you can either modify the prefilled values or just confirm the dialog to finally create the timeperiod.
