[merged] pr #4: compatibility with recent autotools and gcc

ZABOS-150: "text" property must be base64 encoded ...

[fixed] POCSAG messages with enabled encryption brake the deserializing of JMS messages.
ActiveMQs TextMessage implementation is not able to deserialize a String property set with setStringProperty() if the string contains control characters like 0x13 or 0x00.
Therefore the "text" property of the JMS messages is now decoded by using a simple base64 encoding scheme.

[fixed] Unit tests are runnable again
[removed] Disabled integration tests

Removed invalid gcc compiler settings

- added error log if plug-in initialization fails
