[Yanel-usage] Login Screen supports now i18n

[Michael Wechner]

Greetings

As some of you might know, one can overwrite the login screen as 
described in

http://www.yanel.org/en/documentation/security/login-screen-customization.html

With the newest Yanel version (from git) one can now also make use of i18n.

See for example:

src/realms/from-scratch-realm-template/data-repo/data/i18n-from-scratch-realm.xml
src/webapp/xslt/login-screen.xsl

We should refactor the login screen customization be replacing it with 
an overwritable global resource,
but for the moment the above improvements should at least help you to 
i18n your custom login screen just as well.

Thanks

Michael
