recurrence integer fix

[ghost]

• Fix for Possible bug in Recurrence class #380
• MonthlyPattern and YearlyPattern methods try to read XML value using int.class instead of Integer.class.

reader.readElementValue(int.class);

• Correct form should be (used everywhere else in the class):

reader.readElementValue(Integer.class);

This had caused errors in parsing of XML
