Fix archivable behavior when archive table is in another database.
There is a nasty bug causing the `archive()` method to use the wrong connection when called after `delete()`
(this is because we want to enclose the two operations in a transaction when they operate on the same database)
so we need to remove the connection parameter in case the user uses cross-databases archives.
A unit test for this case is quite heavy to set up (two more DBs to create), but I have tested it locally and it is OK.

Introducing Criteria::RAW operator (WIP)

This new operators allows a PDO-like binding, specifying a clause and a
binding type. For instance:

```
$c->add('foo = ?', 123, Criteria::RAW, PDO::PARAM_STR);
```

This is especially necessary for `having()` clauses, because the
conditions are often based on calculated columns, for which Propel
cannot guess the binding type.
Add the ability to create a raw Criterion to all Criteria methods
Remove just added methods.

This shouls keep the Criteria API to a fairly limited number of methods, although it now behaves a little more magically than before. But doing things the proper way requires a more important refactoring, which can happen in Propel2 but not anymore in the 1.x branch
