Add support for inserting table-sorting and filtering option in the table-properties UI

Currently in the CKEditor, for a user who is not savvy with source-syntax, to insert table sorting and filtering option, they have to switch to source mode and copy-paste the velocity script to insert the sorting/filtering option (as mentioned here: http://extensions.xwiki.org/xwiki/bin/view/Extension/Table+Sorter). Most non-tech users won't know how to do this.

In order to simplify this, I suggest providing a check-box option on the Table properties UI itself. There can be 2 checkboxes: 1) to make all tables sortables, and 2) to make all columns filterable. If user selects either of the options, then that macro gets automatically applied to the table. This will make it really easy for users to apply this super-useful feature on the table.

In terms of priority between sorting and filtering, sorting is the more frequently used and asked feature. So I would prioritize that over filtering.

Thanks.
