Move plugins specific configurations to the plugins files

[Frederico Caldeira Knabben]

The default configurations for each plugin must be defined inside each plugin.js file, not into the core config.js file. Just core settings should go into that file.

The motivation behind it is that the core config.js file will be always part of the compressed version of CKEditor. So, if I reduce the number of plugins when building the compressed version, I should not have plugin specific stuff being included in the process.

The patch is almost good. Just two small things:

• The "magnetDistance", "backgroundCoverOpacity" and "backgroundCoverColor" configurations must also be moved. They are specific to the "dialog" plugin.

• Code style: All configuration setting statements are missing the semicolon after the literal object definition. (e.g. line 38 in plugins/table/plugin.js)

Another detail... please always create the patch from the root of the prototype, not the _source folder.

Fixed with [2938]. Sorry for taking the commit to me... just to avoid release delay.
