@Stephen

When using your patch and with a deamon thread I still get a thread hanging while stopping
Camel.

> The camel-stream component is documented to support file and url parameters, but the
code in the StreamEnpoint.java file didn't allow these properties to be set. This patch also
adds the feature of keeping a text file open and reading lines from it as they are written
by other processes or applications.
