FIX: WebFactory failed to initialize on Windows
* getRealPath now throws XFormsConfigException
* using context classloader for resolving resources
* added missing slash to start of betterform config path in web.xml
* hard-coded alternative in XFormsFilter to initialize config (just for later reference)
- prevent possible NP
- removed unused resourcePath2
