Let FacesViews support MultiViews

[BalusC]

MultiViews support is added. It's basically a matter of suffixing the org.omnifaces.FACES_VIEWS_SCAN_PATHS value with /* like so

<context-param>
    <param-name>org.omnifaces.FACES_VIEWS_SCAN_PATHS</param-name>
    <param-value>/*.xhtml/*</param-value>
</context-param>

The path parameters are due to technical limitations unfortunately not available by request.getPathInfo() (as JSF itself internally uses it). But @Param has been enhanced to support injecting path parameters via new @Param(pathIndex) attribute.

Given an URL of http://example.com/context/foo/bar/baz on which neither /foo/bar/baz.xhtml nor /foo/bar.xhtml exist but /foo.xhtml does exist will forward to /foo.xhtml and path parameters are injectable in associated managed bean as below

@Inject @Param(pathIndex=0)
private String bar;

@Inject @Param(pathIndex=1)
private String baz;

@Param built-in conversion/validation is also supported on them.
