Title: Update Travis to test against PHP 5.5

Switch out PHP 5.4 for 5.5. Other option is to add 5.5 as another version to test against and leave 5.4. Went this way so tests don't take longer to run and we're testing against the minimum supported version (kinda, it's 5.3 latest) and the latest version.
