Add recurring issues to Mantis

[administrator]

This plugin incorporates recurring "calls" into Mantis. The field "severity" is renamed to "Call Type" and in addition to the existing definition, 6 types are added : 74:Daily Recurring task 75:Weekly Recurring task 76:Monthly Recurring task 77:Quarterly Recurring task 78:Half-yearly Recurring task 79:Yearly Recurring task If a call (issue) in the system reaches a predefined Status (default: resolved), it creates a new call, again with a predefined status(default: assigned). It then sets a new duedate based upon call type, ie type=76, it adds one month to the duedate. It does work only with the standard working days which means that a month is defined as 22 working days.
