[Number-phone] Number::Phone build system update

[David Cantrell]

For those of you using the build scripts that are in the Number::Phone 
Github repository, I have fixed a bug that meant you needed a recent 
version of Number::Phone installed to have builds work:
   https://github.com/DrHyde/perl-modules-Number-Phone/issues/27

You can also see the current status of the 'master' branch in Travis-CI 
now, which will automagically test it against perl Ancient and Modern 
whenever there's a change:
   https://travis-ci.org/DrHyde/perl-modules-Number-Phone/builds

It *should* also automatically test any pull requests on Github.

For now you'll need to click through to see the details for each build, 
as there are some spurious errors when I try to generate coverage reports:
   perl 5.8 last night:
     https://travis-ci.org/DrHyde/perl-modules-Number-Phone/jobs/55244460
   perl 5.20 last night:
     https://travis-ci.org/DrHyde/perl-modules-Number-Phone/jobs/55244461

If you're not already using Travis and Coveralls for any of your open 
source projects, then I recommend them. Breno de Oliveira wrote up some 
instructions here:
