HtmlConverter needs to reflect naming changes in 1.4.1 and later

For 1.4.0 and earlier, the autodownload binaries were named as
follows...

jinstall-1_3_1_01-win.cab
jinstall-1_3_1_01.ini

jinstall-1_3_1_01a-win.cab
jinstall-1_3_1_01a.ini

jinstall-1_3_1_02-win.cab
jinstall-1_3_1_02.ini

jinstall-1_3_1_03-win.cab
jinstall-1_3_1_03.ini

jinstall-1_4_0-win.cab
jinstall-1_4_0-win.ini

jinstall-1_3_0_04-win.cab
jinstall-1_3_0_04.ini

jinstall-1_3_0_05-win.cab
jinstall-1_3_0_05.ini


The naming convention for 1.4.1 has changed to support the itanium
platform. The new names for the 1.4.1 autodownload binaries are...

jinstall-1_4_1-windows-i586.cab
jinstall-1_4_1-windows-i586.ini

The HtmlConverter program is sensitive to the JRE that is used to
run it. If the JRE used to run the converter is 1.4.1 or later,
the new name should be used in the generated html. If the JRE
used to run the converter is earlier than 1.4.1, then the existing
naming convention should be generated.

Additionally, the make/ishield/jre/Makefile may need to be modified
to ensure that the contents of the jinstall*.inf and jinstall*.ini
reflect the new naming convention as well.

The changes should be tested by completing autodownload testing
as specified by Java Plug-in SQE. They have a way of testing
without having to post publicly.
