LinkToHandler localized Closes #28

This PR depends on the caelum/vraptor4#702

Is right to downgrade from @ApplicationScoped to @RequestScoped, since that it depends on the JstlLocalization?

This feature is new and does not have a final release. The documentation describes the fixed locale prefix as the new implementation, but I implemented with regex to flexible use.

But when I wrote this PR with regex on the route the linkTo returns it, being needed string replace and get from the request URI the locale prefix that the user choosed. I think that is cleanest using the tag language as default.

What do you think?
