Wysiwyg mod

This will enable the `menubar` to shown and use an alternative `skin`

keystone skin doesn't have buttons symbols for additional symbol.
added options:
`'wysiwyg override toolbar'`- override existing buttons (good for rearrangement)
`'wysiwyg menubar'`- show the menubar
`'wysiwyg skin'`- change skin
use example:

```
'wysiwyg override toolbar': false,
'wysiwyg menubar': true,
'wysiwyg additional buttons': 'searchreplace visualchars, charmap ltr rtl pagebreak paste, ' +
   'forecolor backcolor, emoticons media, preview print ',
'wysiwyg additional plugins': 'example, table, advlist, anchor, autolink, autosave, bbcode, charmap,    contextmenu, directionality, emoticons, fullpage, hr, media, pagebreak, paste, preview, print, searchreplace, '    + 'textcolor, visualblocks, visualchars, wordcount',
    'wysiwyg skin': 'lightgray',
```
