Range parameters not consistent with normal iDempiere behavior

[CarlosRuiz-globalqss]

Normally range parameters are managed like this:

• when the first editor is filled and the second editor is empty - operation >= firsteditor
• when the second editor is filled and the first editor is empty - operation <= secondeditor
• when both editors are filled - operation >= firsteditor and <= secondeditor

Also, the parameter is working for Date, but not for Date+Time, because is truncating the time
