FrontendManager fails when pdoTools not installed

[joeke]

When testing on an installation without pdoTools I get the following error:
PHP message: PHP Fatal error: Call to a member function setConfig() on null in /var/www/vhosts/modx258/webroot/core/components/frontendmanager/model/frontendmanager/frontendmanager.class.php on line 38"

This is because the pdoTools service cannot be found. The solution would be to add a dependency for pdoTools to your build config or change the code in the frontendmanager.class.php to fallback to the MODX core functions (getChunk etc.).
