modify NewspaperTable columnClasses to be more useful

Currently the NewspaperTable columnClasses with multiple comma separated classes work only with the column tags themselves,
not the resulting html columns in the table. This change allows the html table to have different column classes across all columns in the html table.
Currently, if you declare:
<t:newspaperTable newspaperColumns="3" columnClasses="class1,class2,class3" . . . >
<t:column>
<f:verbatim>A</f:verbatim>
</t:column>
</t:newspaperTable>
all the columns will be class1

<t:newspaperTable newspaperColumns="3" columnClasses="class1,class2,class3" . . . >
<t:column>
<f:verbatim>A</f:verbatim>
</t:column>
<t:column>
<f:verbatim>B</f:verbatim>
</t:column>
</t:newspaperTable>
all the As will be class1 and Bs will be class2

with this change
<t:newspaperTable newspaperColumns="3" columnClasses="class1,class2,class3" . . . >
<t:column>
<f:verbatim>A</f:verbatim>
</t:column>
</t:newspaperTable>
will have the first column class1, the second column class2, the third class3

<t:newspaperTable newspaperColumns="3" columnClasses="class1,class2,class3",class4,class5,class6" . . . >
<t:column>
<f:verbatim>A</f:verbatim>
</t:column>
<t:column>
<f:verbatim>B</f:verbatim>
</t:column>
</t:newspaperTable>
the first A column will be class1, the first B column class2, the 2nd A column class 3, the 2nd B column class4, ...

This makes it more flexible.
