[#2064] Multilangual routes files support

[vadimv82]

Multiple multilangual routes files support.
You can put several routes files into conf folder in a way:
routes.en, routes.fr, routes.ru.
Same route can have multiple urls for different languages.
Useful for SEO.

Some tests will be great too

[xael-fry]

language can be defined on mode character to handle country specific code ex: en_US, en_UK

[vadimv82]

@xael-fry So routes files can have also names like that routes.en_US ?
I will do tests.

[vadimv82]

I added tests, and changed some logic.

Now you can add specific language routes file. For example routes.ru_RU, routes.fr_FR.
Those can contain language specific urls. If you open lang specific url it will rout right action, but also automatically activates language as it is specified in Route, by url. And also will reverse route.
All that is not lang specific, like ajax calls, static content servers e.t.c you can put under "routes" file without lang extension. All those calls will not activate language change.

Can please somebody review my pull request?

@vadimv82 Could you stash your changes?

Jenkins cannot compile the code

    [javac]         matchingRoutes.sort(new Comparator<ActionRoute>() {
    [javac]                       ^
    [javac]   symbol:   method sort(<anonymous Comparator<ActionRoute>>)
    [javac]   location: variable matchingRoutes of type List<ActionRoute>

Seems like some method are missing as you use the interface Comparator

[vadimv82]

I run same build on my machine with ant -buildfile ./framework/build.xml test
And build is succesfull.

I use anonymous comparator

sortedMatchingRoutes.sort(new Comparator() {
@OverRide
public int compare(ActionRoute ar1, ActionRoute ar2) {
if(locale.equals(ar1.route.locale)) return -1;
if(locale.equals(ar2.route.locale)) return 1;
return Integer.compare(Play.langs.indexOf(ar1.route.locale), Play.langs.indexOf(ar2.route.locale));
}
});

It breaks backward compatibility.
I suggest leaving VirtualFile routes untouched and adding a new field List<VirtualFile> internationalizedRoutes. In this case you don't need field multilangRouteFiles.
