The type parameters of Db\Driver::prepare() and the parameters of Db\Statement::run() can now be arrays, which will be iterated over recursively to bind scalar values to the SQL statement.
This simplifies the construction of arbitrary UPDATE statements (the WHERE clause no longer needs to be taken into account) and should make it clearer what is happening in these cases.
It should also simplify the creation of IN() clauses down the road if they become necessary.
- Result->lastId() added as MySQL and PostgreSQL have equivalent functionality
- Adjusted tests accordingly
- Cleaned up Database class to make use of this and getAll()
