Fixes #1272: Add support for using Formatters to SimpleExporter? (aka. table exporter)

Formatters should be stored in the current ItemContext? object as:

ItemContext.setObject("export.formatter.<propertyname>", formatter);

where <propertyname> is the name of the property that are exported. The formatter is cleared after the export and if the same context is used again a new formatter needs to be specified.
