Plugin adds whitespace before doctype

Hi there
I noticed the plugin is adding whitespace before the !doctype tag. I think it’s caused by carriage returns at the end of these three files:
artiss-transient-cleaner.php
includes/clean-transients.php
includes/shared-functions.php

Probably won’t cause many people any problems but for reasons I won’t bore you with it was messing up something on my site – hence the discovery.

All the best
Jon
