REST Assured 1.5

Highlights

Fixed an issue with the PUT method duplicating form parameters as query parameters (issue 137)
Created a ResponseBuilder to make it easier to create new Response implementations. This is useful if you’re working with filters and want to change the response you get from the sever somehow. E.g.
```
Response myResponse = new ResponseBuilder().clone(originalResponse).setBody("Something").build();
```
Added possibility for some more detailed configuration by providing a RestAssuredConfig instance. Right now you can configure the parameters of HTTP Client, Redirect and Log settings. Examples: For a specific request:
```
given().config(newConfig().redirect(redirectConfig().followRedirects(false))). ..
```
or using a RequestSpecBuilder:
```
RequestSpecification spec = new RequestSpecBuilder().setConfig(newConfig().redirect(redirectConfig().followRedirects(false))).build();
```
or for all requests:
```
 RestAssured.config = config().redirect(redirectConfig().followRedirects(true).and().maxRedirects(0));
```
config() and newConfig() can be statically imported from com.jayway.restassured.config.RestAssuredConfig.
Logging has been improved, see below.

Logging has undergone a major change. You can now not only log the response body but also headers, cookies and status line. You can also log the request details as defined in the request specification. Thus the following:
```
given().log(). .. // Log the response body in versions prior to 1.5
```
and
```
expect().log(). .. // Also logs the response body in versions prior to 1.5
```
will now look like this:
```
given().log().body(). .. // Log the _request_ body in versions >= 1.5
```
and
```
expect().log().body() .. // Log the response body in versions >= 1.5
```
You can also log e.g. only headers in the request and the response:
```
given().log().headers(). .. // Log only the request headers
```
and
```
expect().log().headers(). .. // Log only the response headers
```
Previously there was a method called logOnError in both the request- and response specification. This has now been replaced by the following method in the response specification:
```
expect().log().ifError(). ..
```
(issue 81).
getRequestParams() and getQueryParams() now returns Map<String, ?> instead of Map<String, String> in FilterableRequestSpecification.

Allows configuring redirect settings using the DSL (issue 24), e.g.

given().redirects().max(12).and().redirects().follow(true).when(). ..
