Made all tests roughly the same style

[genio]

Hi! I was assigned your module in this month's PR challenge. While reviewing the module, nothing immediately jumped out at me that needed a fix. So, I had to go nitpicking (no- really, really nitpick-y). The test files were all slightly different in their beginnings, so I looked through them and found what seemed to be the most common theme and updated them all accordingly.

Some test files had a shebang line, some didn't. Some had strict and warnings, others didn't. They all now mostly start with a consistent first few lines:

#!perl

use strict;
use warnings;

Two not quite as nitpick-y as the first changes were also made:

• In 00-load.t it seems beneficial to go ahead and BAIL_OUT if the use_ok fails
• And, in test.t and text_vs_data.t, use $x and $y rather than $a and $b as they are special.

Thanks,
Chase

Merged into a different branch so I can run all the tests more easily without updating master.

Assuming all is well (and I see no reason why it won't be) I'll merge into master shortly. Thanks for your contribution.

And lo, all was good, so merged into master
