Disabling the feature of locked layers.

Essentially this feature makes sure that it disables all tools from doing anything
on a layer that is either not editable or not visible.
While this is a great feature, it makes parts of koffice unuasable due to the fact that all apps
support layers (due to it being part of Flake and ODF) but not all apps can handle them.
So you can end up in a situation where showcase or kword has shapes that are uneditable and
there is no GUI to show why and no GUI to fix the situation.
So disabling this feature until we solve this usability bug.
