0008776: Improve the number format handling on jasper report based reports

Description

Current:
* The current approach to handling number formatting is through the NUMBERFORMAT parameter, that is a java.text.DecimalFormat class
* The textfield is of java.lang.String format and the paramter is used in the textfield expression: $P{NUMBERFORMAT}.format($F{somefield})
* This has the problem that when exporting to other formats like MS Excel, the numbers are 'strings' so you cannot make calculations with the cells

Proposed Solution

* Attached you'll find a patch with part of the proposed solution
* There should be a way to make the format map dynamically, so can modifiable
by the consultant
