Indentation of code, pre-check before starting logging and refactoring

I changed the version to 1.1.0-SNAPSHOT. 

I believe that for the next update if you agree: 

- Rename the classes to suit Java / IBM standards: 

WebsphereSslOutInterceptor -> WebSphereSSLOutInterceptor 
WebsphereSslSocketFactoryLocator -> WebSphereSSLSocketFactoryLocator 

- Rename the package name (the main reason would be the _ character [is not encouraged for use in package names]): 

com.xebia.opensource.cxf.websphere_extensions -> com.xebia.opensource.cxf.extensions.websphere
