support for SQL ORDER BY clauses

[heenenee]

Please add support for ORDER BY clauses. If there already is support and I'm not seeing it, please add an example of how to add an ORDER BY clause to a Entity.find query. Thanks.

There is two ways to "order by" entities:

1. Make your find and order it in memory afterward :
   Entity.find { condition }.sortedBy { it.name }
2. Make ordered query and wrap rows:

Entity.wrapRows(
     Entity.dependsOnTables.select { condition }.orderBy(EntityTable.name, false)
)
