Added getters to AST. Removed Production::__call. Added visitor support to AST. (guilherme: dont shoot me yet :-). visitor support doesnt hurt even if we do not use it for SQL generation). Lots of other things.

Refactorings and initial commit/draft of new event handling / configuration / bootstrapping. Still need to remove all the static EntityManagerFactory::getManager lookup calls from the Production classes. The production classes need to have access to the EntityManager of the Query that constructed the Parser. It should be injected into the Parser during construction.

Changed Doctrine_Query to accept a Doctrine_EntityManager instead of a Doctrine_Connection. Updated Doctrine_EntityManager. Updated test cases and included one new passing test case for SELECT generation. Fixed whitespace bug in DELETE and UPDATE statements.

reverting the reorganization done in 3455-3456 in order to make merging my experimental branch to trunk easier.

Preparation for new organization of code in to sub packages. Changed autoload() to work with new structure.

added tests to get complete coverage of Transaction, RawSQL, AuditLog and Query/Having. Related refactorings. Added some getters to be able to test. Also added coverage report for these changes
