Add filtering/sorting capabilities to the {table} macro

With XWIKI-1244 we've added support for filtering/sorting to HMTL tables by adding some class ids. The next step is to add these features to the

macro. This requires a rewrite of that macro as it's currently using Radeox code which doesn't support adding class ids.

Here's a proposal for the format:

{table:sortable|filterable|sortColumns=0,1,2,4|filterColumns=0,1,2,4}

where sortColumns and filterColumns specify which columns are sortable/filterable. By default if filterable is on then all columns are filterable. Same for sortable.
