[BUGFIX] add _loadRealInstance in f:form ViewHelper

If you edit a form containing subproperties of your domain model,
f:form VH will add some hidden fields to identify your related
domain models (__identity).
But in case of @lazy annotations, these fields will not be
rendered because of a missing _loadRealInstance call 
in AbstractFormViewHelper object.

[CLEANUP] Unqoute integer in BackendUserSessionRepository

In the method "findByBackendUser" in BackendUserSessionRepository,
the beuser uid used in the WHERE condition is casted to int and is
then quoted again.
This is not necessary and breaks the SQL for some DBMS.

[TASK] Use FLUIDTEMPLATE for rendering module Configuration

As cleanup and improvement for the backend it is important to remove the
HTML code from the PHP logic. This patch removes the HTML code and uses
StandaloneView to render the content of the module.

The markup was removed as far as possible.

[FEATURE] Introduce read-only column for file mounts

File mount records get a new flag "read only".
