#620 Report Sorting features

[clee1868]

Currently the system (2.5.3b) allows all standard
reports to sort by selected field(s) in the Print
Format Windows -> Sort order tab. However, it does
not give you an option to allow you to sort the
selected field in ascending or descending order (It
takes the default from the report view defined). For
example, if I want to provide a report on top selling
products or top customer (based on invoice inquiry
reports sort by biggest values or quantity) a option
to sort by ASC or DESC (in the Sort order tab)is very
useful. (rather than creating multiple Report views
to achieve the same result)
