Bug: 20486
Added a note about the history of the porting of the "iterate" tag and the
implementation of code to check for "c:forEach" in addition to "logic:iterate".
Also clarified that the Jakarta Taglibs implementation of the JSTL is being
used for the EL engine.

+(Note that the "iterate" tag was originally ported, even with the presence of
