commandline port configuration

[brackxm]

Allow setting port (or all configuration) via commandline.
Example use case: setting the port for running on heroku.
For example this could be done via environment variables or system properties.

S3PROXY_PORT=8080 java -jar s3proxy --properties s3proxy.conf

java -Ds3proxy.port=8080 -jar s3proxy --properties s3proxy.conf

@brackxm Does #16 address your request? You can override the local endpoint with:

java -Ds3proxy.endpoint=http://127.0.0.1:9090 -jar path/to/s3proxy --properties path/to/conf

[brackxm]

Yes, it does.
Thanks

I will include this fix with with S3Proxy 1.2.0. Presently waiting on jclouds 1.8.1 which should release in a week or two.
