[Yanel-usage] User history default implementation

[Michael Wechner]

Hi

I have done a default implementation of the user history, e.g.

https://127.0.0.1:8443/yanel/my-realm/yanel/users/1412880733771.html

which means successful and failed login attempts are being logged.

This also allows to determine when a user did login last time, which for
example
can help to promote recent changes since last login.

Enjoy

Michael
