Add TexLive to Travis Tests

[tkw1536]

This PR updates the Travis tests to run both with and without TexLive installed.

Don't you need a matrix or some such in the yml file? It would be awesome if we can travis-test both the with and without setups, that's really great! I just don't want us to use the no-texlive successes.

Really cool idea!

This already makes a matrix. From the travis documentation:

For Perl projects, env and perl can be given as arrays to construct a build matrix.

You can have a look at the Travis Test for this PR, there are 2*4=8 test cases, for each perl version there is one with TEX=none and one with TEX=texlive

I just don't want us to use the no-texlive successes.

In order for the build to count as passing, all subtests have to pass. That means both with and without texlive, for each given perl version the tests have to succeed.

Super cool! I'm two thumbs up for this then, great upgrade

Btw I would also be for dropping the 5.18 version and adding the latest perl version supported by Travis instead, so that we stay compliant with the latest Perl. My ubuntu has 5.24 wondering if Travis has that too?

[tkw1536]

Travis should have that one too. According to their documentation they use perlbrew which goes up 5.26 I believe.

[tkw1536]

I would update the PR, but I am not sure why the exact versions that are currently tested have been choosen, so I will leave it to you to change travis.yml (allow edits from maintainers is on).

Too bad they don't have a way to specify all perls back to 5.10 (say). I'd certainly like to test against the newest perls! I don't recall who wrote the original travis.yml, but I'd forgotten about its existence until I needed to disable 5.10 for some XS testing. But since this patch does (at least) double duty, I wonder if we should prune some of the middle versions? 5.14, 5.20, 5.24 or something? I'd hate to overstay my welcome with travis :>
