Subject: Take advantage of PHP 5.4+ short echo (#2585)

* Take advantage of PHP 5.4+ short echo

https://php.net/migration54.new-features thanks to
https://github.com/FreshRSS/FreshRSS/pull/2495

Use `<?=  ?>` instead of `<?php echo; ?>`
10kB of code saved :-)

Done with regular expression:
```
<\?php echo (.+?);? *\?>
<?= \1 ?>
```

* Try Travis fix
