Redmine

Currently the reminder rake task will search for issues that are due in x days in the future without checking the working days configuration of redmine

The attached patch introduces a new argument for the rake task: respect_nonworking_days. When this argument is TRUE, the working days setting will be respected when calculating the days in the future. E.g. when 7 days are requested and in this period are 2 non working days, the query will search for issues that are due within 9 days.
