[Yanel-usage] User profile language is now take into account within Menu

[Michael Wechner]

Hi

One can define a user profile language as below

<user id="test" xmlns="http://www.wyona.org/security/1.0">
  <name>Test User</name>
  <description>Test User</description>
  <email>test at wyona.com</email>
  <password type="md5">dsdsdsdfsdfsdfsdfsdf</password>

  <language>en</language>
  <expire>2069-02-16T00:00:00</expire>
</user>

and if this language is set, then it will now be used for i18n within 
the Yanel toolbar menu.

If it is not set, then the requested language will be set (e.g. browser 
language, etc.)

This hopefully helps to improve the usability of the Yanel toolbar re i18n

Cheers

Michi
