Some optimization. Here are the details:

* SQLDict_assignMessage.zsql

Avoid unnecessary assignments. Reduce message size.

* SQLDict_setPriority.zsql

Reduce message size.

* SQLDict_readMessageList.zsql

Remove unnecessary GROUP BY.
Add uid into ORDER BY so that messages are enumerated
mostly in the order of insertions, which potentially reduces
chances that messages will be reordered later.

* SQLDict_readMessage.zsql

Use DISTINCT and GROUP BY, only if necessary.
Add uid into ORDER BY for the same reason as above.

* SQLDict_createMessageTable.zsql

Specify NOT NULL whenever possible to reduce data size.
Use SMALLINT instead of INT for processing_node to reduce data size.
Remove useless indexes to reduce the cost of UPDATE.
