This is a large push. Included are :

* multi-table updates
* new paid feature for limiting number of queries per hour for users
* optional syntax for multi-table deletes
* optimization for SQL_CALC_FOUND_ROWS
* a small addition for CREATE .. SELECT that will be of future use

I know that all this will require many additions to documentation, 
which I have not done, but I am at Arjen's disposal to help him document
all this.

  Optimisation for SQL_CALC_FOUND_ROWS, when a query involves a single
  table, without WHERE or GROUP clause

  Many things :
  * multi-table updates
  * limiting number of queries per hour for users

    from the one demanded by user. USING clause MUST include ALL tables, 
    not just the ones that are used and not deleted from.
