report period selection

currently the system provides reports for "this month" "this year" or similar

in fact these reports are usually only "complete" for a few moments at the end of the month/year and not accessible any more if the current date moved to the next period.

IMHO most reports will be done for "past" periods so OpenERP should provide a standardized wizard to allow selection of the past period(s) with the option to select multiple periods - Example 3 month periods turnover for quarterly reports
