Lots of cleanup, removal of "foo" variables which are opaque.

  default values!

* Added support for CREATE VIEW + tests in the sqlite producer (groditi)

  Producer (ribasushi)
* Using DROP VIEW instead of OR REPLACE clause in the Pg producer, as replace

  producer (wreis)
* Removed source_db and target_db accessors from Diff (throwback to old version,

  producer, because of a change to DBIx::Class to produce such long names in 
  some cases.

# 0.0899_02 2008-01-29
# ----------------------------------------------------------

* Major refactoring of SQL::Translator::Diff again:
* Diff is no longer one huge monolithic function.                         
* Added more tests for diff                                               
* When producing diffs for MySQL you will (by default) get single alter 
  statements per table
* SQLite can also do remove columns (by creating a temp table as shown in 
  http://sqlite.org/faq.html#q11
* Columns can be renamed if the new schema is from a form that can have metadata
  (which is pretty much anything but an SQL file.) It does this by looking at 
  renamed_from in the $field->extra                              
* Updated Oracle and Postgres producers
* More tests!

# -----------------------------------------------------------
# 0.0899_01 2007-10-21
# ----------------------------------------------------------

* SQL::Translator::Diff now uses the ::Producer modules to create diffs
  This *will* break back-compatibility
  Use sqlt-diff-old for the previous one, and fix producers!

    - Variables and config can be passed on the command line
      with --tt-var and --tt-conf options to sqlt.

*   Added schema filters.
