PHP 5.5 CI, don't allow failures for sqlite3 and postgres
Use preg_replace_callback over preg_replace with e modifier
API HTTP::urlRewriter with (string)$code deprecated in 3.1. Fixed regressions and CSS urls.

urlRewriter will expect a callable as a second parameter,
but will work with the current api and simply raise a deprecation error.

HTTP::absoluteURLs now correctly rewrites urls into absolute urls. Resolves introduced in c56a80d6ce

HTTP::absoluteURLs now handles additional cases where urls were not translated.

Test cases for HTTP::absoluteURLs added for both css and attribute links.

Cleaned up replacement expression and improved documentation.

FIX: Have ParameterConfirmationToken work regardless of include path
Split Core.php into Constants.php and Core.php and adjust main.php startup

The recent flush filter fix had a problem that you couldnt set a custom
BASE_PATH in _ss_environment because that file didnt get included until
after checking the confirmation token. This patch pulls the part of Core.php
that defines BASE_PATH into a seperate file that can be included earlier
in the startup sequence so that ParameterConfirmationToken can access it.

Core.php includes Constants.php with a require_once call, so for startup
scripts that dont pull in Constants.php themselves (like cli-script.php)
no change is needed.
FIX Only suppress fatal errors
