link plugin is missing dependency of htmldataprocessor

[Scott González]

The link plugin requires the htmldataprocessor plugin in order to properly create links, but the link plugin does not list the htmldataprocessor plugin as a dependency.

If you load the link plugin, but not the htmldataprocessor plugin, you will still see the behavior reported in #3928.

Have to say it's not really a bug, 'link' plugin should be considered as been enhanced by 'htmldataprocessor' instead of relying on it - it will continue to function, in case the other exist, it provide a better experience:

var dataProcessor = editor.dataProcessor,
	dataFilter = dataProcessor && dataProcessor.dataFilter;

if ( dataFilter )

That's the way we understand our plugin dependencies.

In 3.0.1, link did depend on htmldataprocessor to function properly. This seems to have been fixed (tested against 3.2.1).

In 3.0.1, if you included the link plugin, but not the htmldataprocessor plugin you would get elements like this:

<a _cke_saved_href="http://example.com" href="javascript:void(0)/*274*/">test</a>

Instead of:

<a href="http://example.com">test</a>

The resolution should be changed from invalid to fixed.
