Terrible Hack to avoid extra context menu entries

Eclipse Editors are often associated with a file, specifically IFile which is an IResource. Depending on what else is included in the overall product, the context menu of such editors will then receive certain menu entries that don't make sense to the end user:

• Team support adds "Team", "Compare With", "Replace With" even though your editor may not really participare in team and local history.
• org.eclipse.debug.ui adds "Run As", "Debug As" even though your editor may not represent anything "runnable"
• PyDev adds more python-refactoring code even though your editor has nothing to do with python

When inspecting for example org.eclipse.debug.ui/plugin.xml of Eclipse 3.7.2, it turned out to contribute the "Run As" context menu for any editor input that adapts to IResource.

To avoid such context menu entries, we wrap the actual editor input into something that does not adapt to a plain IResource, but otherwise forwards to the original IEditorInput. When the editor wraps its input (received in init() and maybe set in saveAs() the nonapplicable context menu entries can be avoided - at least with Eclipse 3.7.2 for team, debug.ui and PyDev; it is a hack after all.
