Patch Proposal: Display warning on including denied depending on INCLUDEWARNING var

Motivation

Including a topic with no proper read permissions for that topic ends up in including a text fragment like "No permission to read topic...". Quite ugly in some cases.

Description

In case of "view permission denied" TWiki interprets the INCLUDEWARNING var and displays a warning according to that.

Documentation

not necessary

Examples

%INCLUDE{"SomeWeb.SomeTopicWithNoReadPermissions" warn="off"}%

Implementation

This patch needs to be patched if the specs of readTopicRaw() change.

Note: Patch is attached as TWiki.pm.IncludePermission.diff. The patch is against the SVN rev #3266.
