Include files safely in functions.php

[carlesjove]

When generating files, a require {file} is added to functions.php. Also, when installing Aina to the theme. However, it's currently added at the last line, which may cause issues if the file has a closing php tag ?>.

Thus, whenever a file is included in functions.php it'd be better to simply include the file after the opening php tag. Genius, uh?
