[MERGE] Perform auto-join and mailboxes+needaction speed udpate. Server-side branch, holding a refactoring of expression.parse and the addition of _auto_join feature on relational fields.

expression.parse: refactored the main parsing loop, now using source and result stacks. Leaf elements are encapsulated into a specific object, allowing to delegate the join condition formation, working table management and table aliases generation to them. The parsing is now a simple loop taking a leaf, doing one action on it, and putting the result back to be analyzed or in the results. This allows to avoid having nested loops and uncontrolled results.

Other modifications :
- updated the generation of order_by to take into account the table now referred using aliases
- updated Query object to use the aliases
- fixed an outstanding bug about _order, now handled as order. This means that putting direct SQL into _order of models will not be supported anymore, because of the computing complexity now that we have multiple joins in queries. The branch holds the patch from Paulius Sladkevičius
- updated and added tests
- added a basic documentation for the freature
