Switched to Encryptors.noOpText(), because of Illegal-key-size-issue

Spring requires a key-length of 256 bits, which is not available in the
JDK, because of US-export-restrictions.

Because Spring Security does not enable the configuration of the key-length,
the build was switched to a NoOpTextEncryptor, to circumvent this issue.

The only other easy way would have been, to require the user to install the
missing parts of the JDK by hand...

See http://stackoverflow.com/a/17637354 for a full explanation.
