stripping html during sorting could be really slow: the added sortProperty
attribute should provide the same functionality with a lower overhead

Description:
Often times it is necessary to allow for a conditional use of the href
attribute on a column (creating a link, or not creating a link, based on the
contents of the column). However, if the link is created manually inside the
contents of the column tag (as opposed to using the href attribute on the
column) the sorting functionality is affected because it now includes the html
markup in the value of each column.
Example:
<display:column property="id" sortable="true">
<c:if test="${not empty row.id}"><html:link
action="ViewItem?id=${row.id}"><c:out value="${row.name}"/></c:if>
<c:if test="${empty row.id}">[empty]</c:if>
</display:column>
Output:
<a href="/app/ViewItem?id=6">Mountain Bike</a>
[empty]
<a href="/app/ViewItem?id=3">Canoe</a>
<a href="/app/ViewItem?id=8">Tent</a>
[empty]
The problem with the above code is that the sort will actually occur on the
value of the id rather than the name. However, since the end user sees a name
in the column, that person would expect it to be sorting on name. Under no
circumstance would a sort on the url be desirable.
