Scytale v1.0.1

Bugfixes

• Issue #5 Some of exceptions return null in getMessage() method. This was causing native Log to crash. Now if any exception during encryption, decryption or key manipulations occurs Scytale will print short error log to logcat with exception class name and exception message, if last exists. Use Crypto#setErrorListenerand Store#setErrorListener methods to get more information about errors.
