Moving to OSGi bundle

[Dop Sun]

Jassandra moves to provide the OSGi bundle output, details here:
http://code.google.com/p/jassandra/issues/detail?id=30

Along with change, the following changes will be added:
1) Deprecated the ByteArray.ofUUID and ByteArray.toUUID: since it's
directly exposing the UUID implementation. Details at
http://code.google.com/p/jassandra/issues/detail?id=32

Currently, this API just marked as deprecated, but it may be released
soon in future release to make the library small and clean.

Internally, org.safehaus.uuid.UUID still be used to generate the type
1 UUID. A new API will be added to the org.softao.jassandra.utils, to
provide the capability to create the java.util.UUID with the Type 1 by
using org.safehaus.uuid.UUID.

Feedback, comments are welcome.
