Swagger should not require init-params

[rage-shadowman]

Swagger should not require init-params for configuration.

The user may be using annotations to determine everything and not have any need for a servlet entry in web.xml. A set of context-params should be sufficient for configuration or even just a context-param for a ConfigReader class.

this is part of a larger refactor coming in next major release

In 1.3.0-SNAPSHOT you can initialize swagger with pluggable config readers:

https://github.com/wordnik/swagger-core/blob/develop-1.3/modules/swagger-jaxrs/src/main/scala/com/wordnik/swagger/jaxrs/config/DefaultJaxrsConfig.scala

Uses web.xml (and is default)

https://github.com/wordnik/swagger-core/blob/develop-1.3/modules/swagger-jaxrs/src/main/scala/com/wordnik/swagger/jaxrs/config/BeanConfig.scala

Is a BeanConfig approach which should be loaded before swagger is.
