[FEATURE] Use salted Install Tool password

To enhanced the security this patch changes the Install Tool password
from md5 hash to a salted hashed password. Therefore the default
password in the FactoryConfiguration.php is changed. Old md5 hashes get
converted automatically during the boot process of the Install Tool. The
output of the calculated hash is reintroduced when an error occured.
The report modules were adjusted to be able to check salted hashed
passwords.
