OpenAMF 1.0RC3 Released

RC3 contains:
- improved logging
- improved exception handling
- up-to-date versions of dependencies
- lots of other small fixes and some code clean up

Logging

In order to improve logging 2 new loggers were created org.openamf.REQUEST and
org.openamf.RESPONSE. These are both "virtual" loggers and don't represent a
particular class, but instead log the parsed AMF requests and responses. They
can both be watched at the DEBUG and INFO levels.
