Tested on ICEfaces trunk 19184 + Tomcat6.0

• verified with success on FF3.5, Opera9.64
• testing on IE is blocking by ICE-4223. But if saving the exported file to the correct type (excel in the test app), file also contains correct/expected data.

Test app added to repo\qa\trunk\Regression\ICE-4289

How to use it?
It takes comma separated column indexes. Let say if there are 6 columns in the table and you want to add only 1st, 4th and 6th column to the generated output, the code snippet would look like this:
<ice:dataExporter includeColumns="0,3,5"... >

The column order of the above example can be changed a well:
<ice:dataExporter includeColumns="5,0,3"... >

By default all columns will be included to the output in the default order.

Note: index is 0 based.

new attribute added to the dataExporter component named as "includeColumns", Which lets you specify the order and # of columns to be added to the generated output.
