Fix sidebar height in styles.

There was some inconsistency with sidebar height definition in styles,
it is fixed now.

that has clear:both set to be present next to the sidebar, not below
it.

v1.0.0.dev12

Fixed 500 error when no permission to module

Error was occuring when user had no permission to module that was added to menu
due to missing code for handling None elements in menu (that are returned on
such conditions, so items that user has no permissions to won't have entries
displayed in menu).
