Added SL59 i386 templates

Relates to #542 the tests all pass for this pull request.

I didn't expect to have some free time to setup a 32bit version of this template.

I'd like to mention that the vbox additions in the 32 and 64bit versions of this distro fails to compile the "advanced graphics" driver, but that probably doesnt matter for this use case. Either which way, the kernel is too old to compile the driver so its a soft failure/warning.

As such, the script doesnt always clean up the .iso file that gets downloaded.
