[fix] Apply fulltextindexed change in the actual index Change of the fulltextindexed attribute of a CWAttribute did actually change anything for already existing entity (but apply to new one). This patch fix this behaviour: * A new SingleLastOperation, UpdateFTIndexOp, to reindex entity whose ftindexation changed during a commit. This data is read from session.transaction_data['fti_update_etypes'] * The SourceDbRDefUpdate operation to store Etype who modify they fulltextindexed of attribute in session.transaction_data['fti_update_etypes']. * A new test is added to check the behaviour

/* XXX limit_size version dealing with format as postgres version does.
   XXX mysql doesn't support overloading, each function should have a different name
       
   NOTE: fulltext renamed since it cause a mysql name conflict
