Perl 5.8 image

Granted perl 5.8 is not supported officially, but that's the same with 5.10/12 anyway, and 5.8 is still reasonably well being used at the production and majority of the CPAN module authors still support it.

It's great if we can test to see if a module builds properly using Travis + 5.8.
