User template

[borisbrdaric]

It should be possible to define 'user template' by using admin Wirecloud account in order to provide pre-configured Wirecloud environment with specific welcome screen, widgets, mashups, tutorials, language, etc. Wirecloud admin would be able to assign 'user template' to a new Wirecloud user.

In addition, Wirecloud should provide API which could be used by other applications to programmatically assign user templates to new users.
